[[The Doctor]], throughout many of their lives, possessed a '''sonic screwdriver'''. They ostensibly upgraded and improved each subsequent model, improving functionality and adding additional features while the design changed. Features included projecting [[sound]] waves to lock or unlock [[door]]s, frying [[circuitry]], [[hacking]], disabling, and activating technology. It could also be used as a [[scanner|scanning device]], with medical applications.
 
Each model used the same [[software]]. Essentially, the sonic screwdriver in use by the [[War Doctor]] was the same as that in the [[Eleventh Doctor]]'s possession, some 400 years later. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')
 
At least one version of the screwdriver used a [[crystal]] similar to the [[Metebelis crystal]] sought after by the [[Eight Legs]] of [[Metebelis III]], ([[COMIC]]: ''[[The Forgotten (comic story)|The Forgotten]]'') while the [[Fifth Doctor]] attempted to collect a [[diothynine crystal]] from the planet [[Argentia]] where temporal zone met to focus sonic waveforms for a new sonic screwdriver. ([[AUDIO]]: ''[[Serpent in the Silver Mask (audio story)|Serpent in the Silver Mask]]'') There were also electrical components. ([[COMIC]]: ''[[The Halls of Sacrifice (comic story)|The Halls of Sacrifice]]'')
 
The screwdriver had a multitude of settings and different versions of settings. The [[Tenth Doctor]] told [[Rose Tyler|Rose]] to use "[[setting 15B]]" to triangulate the source of the ghosts ([[TV]]: ''[[Army of Ghosts (TV story)|Army of Ghosts]]'') and used [[setting 34-H|34-H]] to sink a ship. ([[COMIC]]: ''[[Second Wave (comic story)|Second Wave]]'') It had a [[setting 85]] that undid security codes to unlock [[door]]s. ([[TV]]: ''[[The Lazarus Experiment (TV story)|The Lazarus Experiment]]'') The [[Ninth Doctor]] told Rose to use [[setting 2428D]] to re-attach [[barbed wire]]. ([[TV]]: ''[[The Doctor Dances (TV story)|The Doctor Dances]]'') [[Sarah Jane Smith|Sarah Jane]] used the [[Theta Omega setting]] to melt [[plastic]] [[vine]]s. ([[TV]]: ''[[The Android Invasion (TV story)|The Android Invasion]]'') The [[Twelfth Doctor]] told [[Clara Oswald|Clara]] to use [[setting 41]] to send out random bursts of [[helicon energy]] to distract the [[Skovox Blitzer]]. ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'') The Twelfth Doctor himself used [[setting 61]] to knock out a [[Cybernetics|cybernetically]] augmented [[dinosaur]] with a "[[sonic brainstorm]]". ([[COMIC]]: ''[[Spirits of the Jungle (comic story)|Spirits of the Jungle]]'') However, at least one version of the screwdriver was able to use thoughts as well as settings. ([[TV]]: ''[[The Big Bang (TV story)|The Big Bang]]'', ''[[Amy's Choice (TV story)|Amy's Choice]]'', ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'', ''[[Death in Heaven (TV story)|Death in Heaven]]'') The same version could also be activated using the Doctor's voice. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'')
 
The different versions of the Doctor's sonic screwdrivers exhibited different capabilities and uses, such as medical diagnostics ([[TV]]: ''[[The Empty Child (TV story)|The Empty Child]]'') and repair of organic parts; ([[TV]]: ''[[The Vampires of Venice (TV story)|The Vampires of Venice]]'') cutting, but also re-attaching materials such as [[barbed wire]]; ([[TV]]: ''[[The Doctor Dances (TV story)|The Doctor Dances]]'') operating Earth machinery such as [[computer]]s ([[TV]]: ''[[School Reunion (TV story)|School Reunion]]'') and even [[cash machine]]s (at regular and high eject speeds); ([[TV]]: ''[[The Runaway Bride (TV story)|The Runaway Bride]]'') creating a [[spark]] to light a [[candle]] ([[TV]]: ''[[The Girl in the Fireplace (TV story)|The Girl in the Fireplace]]'') or [[Bunsen burner]]; ([[TV]]: ''[[Evolution of the Daleks (TV story)|Evolution of the Daleks]]'') opening and holding doors with acoustic [[lock]]s; ([[TV]]: ''[[The Rings of Akhaten (TV story)|The Rings of Akhaten]]'') and, on the rare occasion, driving [[screw]]s without touching them. ([[TV]]: ''[[The War Games (TV story)|The War Games]]'', ''[[The Ark in Space (TV story)|The Ark in Space]]'', ''[[The Doctor's Wife (TV story)|The Doctor's Wife]]'')
 
[[River Song]] told the [[Fourth Doctor]] that, though his current screwdriver was mostly just a screwdriver, he would later "go a bit crazy with the optional upgrades". ([[AUDIO]]: ''[[Someone I Once Knew (audio story)|Someone I Once Knew]]'')
 
Although it was primarily a tool, the sonic screwdriver could also be used as a defensive weapon, able to combine with other [[sonic device]]s to form a shield around a hostile target to either force them back ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') or slow their advance. ([[TV]]: ''[[The Doctor Falls (TV story)|The Doctor Falls]]'') The Tenth Doctor put it in a soundboard to destroy the [[Robot Santa]]s by overloading their sensors. ([[TV]]: ''[[The Runaway Bride (TV story)|The Runaway Bride]]'') The [[Eleventh Doctor]] used it to bounce sound waves off a knife held by [[Melody Pond]], knocking it out of her hand. ([[TV]]: ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'') The sonic screwdriver was also capable of holding off sound waves from creatures who relied on sound in order to attack such as the [[Vigil]]. ([[TV]]: ''[[The Rings of Akhaten (TV story)|The Rings of Akhaten]]'')
 
The sonic screwdriver would, in rare occasions, be used as an offensive weapon, firing energy blasts. The Eleventh Doctor used it in this manner to help River Song defeat a group of [[Silent]]s, defeating at least two of them. ([[TV]]: ''[[Day of the Moon (TV story)|Day of the Moon]]'') The Twelfth Doctor used the same model of screwdriver to blast a [[Hyperion (species)|Hyperion]], buying himself and others time to escape from it. ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'') It could also destroy ice creatures when it received the latest update. ([[TV]]: ''[[The Snowmen (TV story)|The Snowmen]]'')
 
Although the [[Third Doctor]] used the device to incapacitate [[Space Greyhound]]s by disrupting their brain functions, ([[COMIC]]: ''[[The Forgotten (comic story)|The Forgotten]]'') and the [[Eighth Doctor]] once claimed it could destroy a Dalek's brain if held directly against the casing when activated, ([[PROSE]]: ''[[War of the Daleks (novel)|War of the Daleks]]'') according to the Tenth Doctor, the device could not be used to wound, maim or kill living things. ([[TV]]: ''[[Doomsday (TV story)|Doomsday]]'', ''[[The Doctor's Daughter (TV story)|The Doctor's Daughter]]'') It could destroy non-living objects or mechanisms or place living creatures in circumstances where they might die if the situation required. ([[TV]]: ''[[The Christmas Invasion (TV story)|The Christmas Invasion]]'') The [[War Doctor]] claimed that it was a scientific instrument rather than a [[water pistol]], ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') or indeed a [[magic wand]]. ([[PROSE]]: ''[[The Day of the Doctor (novelisation)|The Day of the Doctor]]'')
 
Particularly during the [[Time War]] ([[AUDIO]]: ''[[The Satanic Mill (audio story)|The Satanic Mill]]'', ''[[The Thousand Worlds (audio story)|The Thousand Worlds]]'', ''[[The Heart of the Battle (audio story)|The Heart of the Battle]]'', ''[[A Thing of Guile (audio story)|A Thing of Guile]]'') and in their thirteenth incarnation, ([[COMIC]]: ''[[A New Beginning (comic story)|A New Beginning]]'', [[TV]]: ''[[The Battle of Ranskoor Av Kolos (TV story)|The Battle of Ranskoor Av Kolos]]'') the Doctor was known on occasion to summon [[the TARDIS]] using their sonic screwdriver, though the [[Thirteenth Doctor]] noted that the TARDIS got "prickly" at being summoned too often, as she found it demeaning. ([[COMIC]]: ''[[A New Beginning (comic story)|A New Beginning]]'')
 
For a time, the Twelfth Doctor abandoned sonic screwdrivers in favour of wearable technology - namely, his [[sonic sunglasses]]. ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'', ''[[Under the Lake (TV story)|Under the Lake]]'') However, after briefly returning to [[Gallifrey]] he resumed using them, as his TARDIS fashioned a new one for him as a gift. Furthermore, after the Doctor had lost sight of who he was, [[Clara Oswald]] left him a reminder to "be a Doctor" after leaving his company. As part of his role of being a Doctor was to use a sonic screwdriver, the Doctor accepted the TARDIS's gift ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'') though he would continue to occasionally use the sunglasses as well. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'')
 
== The First and Second Doctors' sonic screwdrivers ==
A small, simple [[metal]] rod similar to a penlight, [[sonic screwdriver]] was used by the [[First Doctor]]. ([[PROSE]]: ''[[Venusian Lullaby (novel)|Venusian Lullaby]]'') It was also used by the [[Eighth Doctor]] after being destroyed "centuries ago", with the Doctor claiming to his [[companion]] [[Sam Jones]] that this was possible because "It's a [[Time Lord]] [[tool]]. [[Time]] doesn't work the same way for Time Lord tools." ([[PROSE]]: ''[[Alien Bodies (novel)|Alien Bodies]]'')
 
However, according to one account, the First Doctor did not possess a sonic screwdriver, leaving him confused and somewhat irritated when the [[Twelfth Doctor]] utilised a future model. ([[TV]]: ''[[Twice Upon a Time (TV story)|Twice Upon a Time]]'') Indeed, an [[The Doctor (Sympathy for the Devil)|alternate Third Doctor]] did not recognise the device. ([[AUDIO]]: ''[[The Emporium At The End (audio story)|The Emporium At The End]]'')
 
[[File:Fury from the Deep BBC telesnap 11.jpg|thumb|left|The [[Second Doctor]] using his [[whistle]]-like Sonic Screwdriver ([[TV]]: ''[[Fury from the Deep (TV story)|Fury from the Deep]]'')]]
The [[Second Doctor]] used sonics of different design, including one like a life jacket safety [[whistle]], ([[TV]]: ''[[Fury from the Deep (TV story)|Fury from the Deep]]'') or like a metal penlight ([[TV]]: ''[[The War Games (TV story)|The War Games]]'') which could get a trigger attachment. ([[TV]]: ''[[The Dominators (TV story)|The Dominators]]'')
 
The Eighth Doctor carried a similar rod model near the end of his life: [[Cylinder|Cylindrical]] and [[silver]], with a [[blue]] emitter diode tip, he used it in a surgical procedure to scan his [[patient]] and to seal [[incision]]s. This model could glow with an "almost [[white]]" [[light]] and emit great [[heat]], be used to sharpen surgical instruments and be turned "on" and "off". ([[PROSE]]: ''[[Osskah (short story)|Osskah]]'')
 
A rod version of this screwdriver was kept in the [[Twelfth Doctor]]'s [[The Doctor's office (The Pilot)|office]] at [[St Luke's University]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')
 
=== Uses ===
[[File:Doc2Sonic.jpg|thumb|The [[Second Doctor]] using his [[penlight]] design of sonic screwdriver ([[TV]]: ''[[The War Games (TV story)|The War Games]]'')]]
The First and Second Doctors sonic screwdriver funcioned as a conventional [[screwdriver]], without physical contact with [[screw]]s. ([[TV]]: ''[[The War Games (TV story)|The War Games]]'') It was also capable of cracking [[code]]s, ([[PROSE]]: ''[[Venusian Lullaby (novel)|Venusian Lullaby]]'') opening up hatches, panels, control panels, ([[TV]]: ''[[Fury from the Deep (TV story)|Fury from the Deep]]'', ''[[The War Games (TV story)|The War Games]]'') and [[prison cell]] [[door]]s. ([[AUDIO]]: ''[[Fear of the Daleks (audio story)|Fear of the Daleks]]'') On occasion, the Doctor also used it to cut through a section of a [[wall]] ([[TV]]: ''[[The Dominators (TV story)|The Dominators]]'') and to override a security lock. ([[AUDIO]]: ''[[Helicon Prime (audio story)|Helicon Prime]]'')
 
He also used it to destroy the [[Dalek crystal]] at the heart of a [[mind projector]] ([[AUDIO]]: ''[[Fear of the Daleks (audio story)|Fear of the Daleks]]'') and to dismantle a Hawker. ([[AUDIO]]: ''[[The Apocalypse Mirror (audio story)|The Apocalypse Mirror]]'')
 
== The Third, Fourth and Fifth Doctors' sonic screwdriver ==
[[File:Pertweewithscrewdriver.jpg|thumb|left|The Third Doctor's sonic. ([[TV]]: ''[[Carnival of Monsters (TV story)|Carnival of Monsters]]'')]]
The [[Third Doctor]]'s most-used model of the sonic screwdriver was much larger than the one his first and second incarnation used; its elaborately detailed [[silver]] collar featured [[black]] and [[yellow]] stripes and [[red]] trim, and could be pulled down to activate the screwdriver. It had a removable [[burgundy]] emitter head which the Doctor would change with others, each performing a different function. ([[TV]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'')
 
On one occasion he removed the head entirely and replaced it with a small, round [[mirror]], which spun rapidly when he tapped its edge with his finger and [[hypnosis|hypnotized]] anyone who looked at it. Accompanied by a yellow [[light]] on the collar of his sonic screwdriver and the Doctor singing a Venusian lullaby, it hypnotized the aggressive [[Aggedor]] into calmness. ([[TV]]: ''[[The Curse of Peladon (TV story)|The Curse of Peladon]]'')
 
The Third Doctor later fitted the head of his sonic screwdriver with a cylindrical black magnet which enabled it to open bolted doors, especially when its polarity was reversed. This refit left the metal mostly unpainted, with a dark red emitter ring. The head of this model could be extended. The sonic screwdriver was confiscated when the Doctor was sent to the [[Lunar Penal Colony]], and he never recovered it. ([[TV]]: ''[[Frontier in Space (TV story)|Frontier in Space]]'') However, the Doctor had a spare aboard the TARDIS, which he made use of in the [[Dalek]] base on [[Spiridon]]. ([[TV]]: ''[[Planet of the Daleks (TV story)|Planet of the Daleks]]'')
 
[[File:Four uses Sonic on drone.jpg|thumb|The Fourth Doctor with the sonic. ([[TV]]: ''[[The Sontaran Experiment (TV story)|The Sontaran Experiment]]'')]]
Before this model met its demise, its head was repainted twice after the original coat wore off. ([[TV]]: ''[[The Keeper of Traken (TV story)|The Keeper of Traken]]'', ''[[Castrovalva (TV story)|Castrovalva]]'') It was ultimately destroyed when the [[Terileptil]] leader forced the [[Fifth Doctor]] to drop the screwdriver inside a holding cell, then incinerated it with a blast from a laser gun — causing the Doctor to remark "I feel as though you've just killed an old friend." ([[TV]]: ''[[The Visitation (TV story)|The Visitation]]'')
 
The Doctor went without a sonic screwdriver for some time after this model, with [[Nyssa]] lamenting his decision not to replace it. ([[TV]]: ''[[Snakedance (TV story)|Snakedance]]'') The [[Tenth Doctor]] also lightly mocked his past incarnation for going "hands-free" following this incident when their TARDISes accidentally collided. ([[TV]]: ''[[Time Crash (TV story)|Time Crash]]'')
 
This sonic operated at a frequency of 80 [[kilohertz]]. ([[PROSE]]: ''[[Light Fantastic (short story)|Light Fantastic]]'')
 
The Doctor, leaving [[UNIT]], left behind a prototype. UNIT scientists then tried to use reverse-engineering to understand its workings; this went on into the [[21st century]]. Despite them trying to keep it quiet from the Doctor, he was well aware of the project by his [[Seventh Doctor|seventh incarnation]]. ([[AUDIO]]: ''[[Persuasion (audio story)|Persuasion]]'')
 
A version of this screwdriver was kept in the [[Twelfth Doctor]]'s [[The Doctor's office (The Pilot)|office]] at [[St Luke's University]]. His companion [[Nardole]] made use of it in a [[War zone (The Pilot)|war zone]] where the [[Dalek]]s and [[Movellan]]s skirmished. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')
 
=== Uses ===
The sonic screwdriver was often used for opening doors, ([[TV]]: ''[[The Green Death (TV story)|The Green Death]]'', ''[[The Monster of Peladon (TV story)|The Monster of Peladon]]'', ''[[The Mutants (TV story)|The Mutants]]'', ''[[The Pirate Planet (TV story)|The Pirate Planet]]'', ''[[The Ribos Operation (TV story)|The Ribos Operation]]'', ''[[Four to Doomsday (TV story)|Four to Doomsday]]'') electronic locks ([[TV]]: ''[[Carnival of Monsters (TV story)|Carnival of Monsters]]'') and, once, [[Sutekh]]'s [[deflection barrier]]. ([[TV]]: ''[[Pyramids of Mars (TV story)|Pyramids of Mars]]'') It was also capable of scanning for alarm systems, ([[TV]]: ''[[Colony in Space (TV story)|Colony in Space]]'') and [[radiation]]. ([[TV]]: ''[[The Three Doctors (TV story)|The Three Doctors]]'')
 
On occasion, the Doctor used it to either disarm explosive weapons ([[PROSE]]: ''[[Cold Fusion (novel)|Cold Fusion]]'') or to detonate them. ([[TV]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'', ''[[Robot (TV story)|Robot]]'', ''[[Destiny of the Daleks (TV story)|Destiny of the Daleks]]'') He often used it to either detect or interfere with circuitry and technology overall. ([[TV]]: ''[[Frontier in Space (TV story)|Frontier in Space]]'', ''[[Planet of the Daleks (TV story)|Planet of the Daleks]]'', ''[[The Sontaran Experiment (TV story)|The Sontaran Experiment]]'', ''[[The Ark in Space (TV story)|The Ark in Space]]'', ''[[The Sontaran Experiment (TV story)|The Sontaran Experiment]]'', ''[[The Sontaran Experiment (TV story)|The Sontaran Experiment]]'', etc.)
 
The sonic screwdriver also functioned as a conventional screwdriver. ([[TV]]: ''[[The Monster of Peladon (TV story)|The Monster of Peladon]]'', ''[[The Ark in Space (TV story)|The Ark in Space]]'')
 
Using the appropriate [[sonic frequency]], the [[Fourth Doctor]] used it to return himself, [[Ernestina Stott]] and later, [[The Doctor's scarf|his scarf]], to normal size. ([[AUDIO]]: ''[[The Dead Shoes (audio story)|The Dead Shoes]]'')
 
The sonic screwdriver also affected alive beings: the [[Third Doctor]] used it to cure [[Henry VIII]] of his [[cataract]]s, ([[PROSE]]: ''[[Hiccup in Time (short story)|Hiccup in Time]]'') distract [[giant maggot]]s, ([[TV]]: ''[[The Green Death (TV story)|The Green Death]]'') break a [[hypnotic]] trance ([[TV]]: ''[[Death to the Daleks (TV story)|Death to the Daleks]]'') and overload the [[brain]]s of [[Space Greyhound]]s. ([[COMIC]]: ''[[The Forgotten (comic story)|The Forgotten]]'')
 
With the screwdriver, the Doctor was also capable of creating a spark of [[fire]], ([[TV]]: ''[[Carnival of Monsters (TV story)|Carnival of Monsters]]'') melting plastic vines ([[TV]]: ''[[The Android Invasion (TV story)|The Android Invasion]]'') and creating loud noises. ([[TV]]: ''[[Four to Doomsday (TV story)|Four to Doomsday]]'')
 
== Used by the Sixth Doctor ==
The [[Sixth Doctor]] once carried an unspecified replacement model for the sonic screwdriver, but had to leave it tied to the side of a video camera in a dungeon cell in order for it to keep the visual feed disabled. ([[PROSE]]: ''[[The Nightmare Fair (novelisation)|The Nightmare Fair]]'') He later carried another sonic model during his adventures with [[Crystal]], [[Jason (The Ultimate Adventure)|Jason]], and [[Zog (The Ultimate Adventure)|Zog]]. ([[AUDIO]]: ''[[The Ultimate Adventure (audio story)|The Ultimate Adventure]]'')
 
=== Uses ===
The [[Sixth Doctor]]'s screwdriver could be used to disable a [[video camera]] indefinitely, ([[PROSE]]: ''[[The Nightmare Fair (novelisation)|The Nightmare Fair]]'') close and seal [[Dalek]] [[door]]s, ([[AUDIO]]: ''[[The Ultimate Adventure (audio story)|The Ultimate Adventure]]'') and repair the [[TARDIS control console]]. ([[AUDIO]]: ''[[The Ultimate Adventure (audio story)|The Ultimate Adventure]]'') He once attempted to use it to free [[Envoy (The Ultimate Adventure)|the American Envoy]] from the Dalek [[laser wall]], but this failed. ([[AUDIO]]: ''[[The Ultimate Adventure (audio story)|The Ultimate Adventure]]'')
 
== The Seventh and Eighth Doctors' sonic screwdriver ==
{{Section stub|As per [[Thread:133842]], there is a sonic in the Doctor's possession by the time of his travels with Benny in the NAs. Info needs to be added from these sources, as well as numerous Big Finish audio dramas.}}
[[File:ChangLooksThroughSonic.jpg|thumb|[[Chang Lee]] discovers the sonic screwdriver amongst the things he stole from the [[Seventh Doctor]]. ([[TV]]: ''[[Doctor Who (TV story)|Doctor Who]]'')]]
The [[Seventh Doctor]] acquired a sonic screwdriver at an unspecified point of his life. Many contradictory accounts existed, including one which claimed he had acquired it at some point before meeting [[Bernice Summerfield]], ([[AUDIO]]: ''[[Love and War (audio story)|Love and War]]'') and another, which claimed he acquired it from himself on [[Silurian Earth|a parallel Earth]] where the species [[Silurian|Homo Reptilicus]] had conquered the Earth and killed [[Third Doctor|his third incarnation]]. ([[PROSE]]: ''[[Blood Heat (novel)|Blood Heat]]'', ''[[First Frontier (novel)|First Frontier]]'') The Doctor himself claimed that he had only recently built one shortly before re-encountering {{Champion}}, ([[PROSE]]: ''[[No Future (novel)|No Future]]'') and that he received it as compensation after suing the Terileptils for [[criminal]] damage. ([[PROSE]]: ''[[GodEngine (novel)|GodEngine]]'') The [[Eighth Doctor]] claimed that this screwdriver was a spare model that had "rolled under the TARDIS console and remained there" until the Seventh Doctor found it. ([[PROSE]]: ''[[Frontier Worlds (novel)|Frontier Worlds]]'')
 
This model, identified as the "Mark 5" by the Eighth Doctor, ([[PROSE]]: ''[[Alien Bodies (novel)|Alien Bodies]]'') looked similar to the screwdriver used up until his fifth incarnation: it was silver with a brass trim ring in the lower grip and a handle that resembled that of the previous sonic screwdrivers', now with a flat base. Its upper section was able to undergo telescopic collapse for ease of carrying, and, at its top, it held an emitter with a silver ring and a red bullet-shaped crystal at its centre. ([[TV]]: ''[[Doctor Who (TV story)|Doctor Who]]'') The Seventh Doctor claimed he patented the sonic screwdriver. ([[AUDIO]]: ''[[The Unknown (audio story)|The Unknown]]'') Once, while suffering from amnesia, the Eighth Doctor was able to operate this sonic screwdriver on instinct. ([[PROSE]]: ''[[EarthWorld (novel)|EarthWorld]]'') This version remained in the Eighth Doctor's use throughout his life, up until its destruction at the hands of a [[Cyber-Leader (The Flood)|Cyber-Leader]] on Earth. ([[COMIC]]: ''[[The Flood (comic story)|The Flood]]'')
 
The Eighth Doctor had resumed using this model by the end of his life during the [[Last Great Time War]]. It was the second and final model the Doctor used thus far that bore an emitter-ring head. ([[TV]]: ''[[The Night of the Doctor (TV story)|The Night of the Doctor]]'') The Eighth Doctor's other choice of a diode-tipped model would become the standard for his later incarnations. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'', ''[[Rose (TV story)|Rose]]'', ''[[The Christmas Invasion (TV story)|The Christmas Invasion]]'', ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'', ''[[Deep Breath (TV story)|Deep Breath]]'')
 
The Eighth Doctor once commented that he felt undressed without his sonic screwdriver. ([[AUDIO]]: ''[[The Sontaran Ordeal (audio story)|The Sontaran Ordeal]]'')
 
A version of this screwdriver was kept in the [[Twelfth Doctor]]'s [[The Doctor's office (The Pilot)|office]] at [[St Luke's University]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')

== Replacement on Ha'olam ==
During his imprisonment by [[INC]] on [[Ha'olam]], the Doctor's sonic screwdriver was confiscated. After his escape, he briefly used a replacement screwdriver resembling a slender metal rod with a crystal at its tip. ([[PROSE]]: ''[[Seeing I (novel)|Seeing I]]'')
 
=== Uses ===
This screwdriver was used by the Doctor for making [[milkshake]]s and [[hacking]] into the [[Ubernet]]. ([[PROSE]]: ''[[Seeing I (novel)|Seeing I]]'')
 
== The Eighth Doctor's second screwdriver ==
[[File:Dark Eyes sonic.jpg|thumb|The Eighth Doctor's second screwdriver. ([[COMIC]]: ''[[The Pictures of Josephine Day (comic story)|The Pictures of Josephine Day]]'')]]
Later in his eighth incarnation, the Doctor carried a sonic screwdriver with a wooden handle. It had a metallic tip with six prongs that nested a clear diode at the end, which glowed blue when activated. ([[AUDIO]]: ''[[The Great War (audio story)|The Great War]]'') Its handle doubled as a torch. ([[AUDIO]]: ''[[Sword of Orion (audio story)|Sword of Orion]]'') The Doctor claimed that he made this version of the sonic screwdriver to do more than open doors and blow up land mines. ([[AUDIO]]: ''[[X and the Daleks (audio story)|X and the Daleks]]'') He later made further modifications to the screwdriver. ([[AUDIO]]: ''[[Beachhead (audio story)|Beachhead]]'')
 
It was referred to as a [[pennywhistle]] by numerous [[World War I]] medics. ([[AUDIO]]: ''[[The Great War (audio story)|The Great War]]'') The Doctor possessed it as early on as his travels with Charley Pollard, ([[AUDIO]]: ''[[The Light at the End (audio story)|The Light at the End]]'') and was still using it in the early part of the [[Last Great Time War]]. ([[PROSE]]: ''[[Natural Regression (short story)|Natural Regression]]'') He had returned to using his original model by the end of his life. ([[TV]]: ''[[The Night of the Doctor (TV story)|The Night of the Doctor]]'')
 
=== Uses ===

== The War Doctor's sonic screwdriver ==
[[File:War Doctor sonic.jpg|thumb|The War Doctor's sonic screwdriver. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')]]
During his battles in the [[Last Great Time War]], ([[COMIC]]: ''[[The Clockwise War (comic story)|The Clockwise War]]'') the [[War Doctor]] used a sonic screwdriver with a simple metallic handle and a red-light-emitting diode at the end. It appeared to be a further upgraded version of the Eighth Doctor's first sonic screwdriver, which he kept strapped in a bandoleer on his chest. It shared the same casing type as the screwdriver used by the Fourth Doctor, but had an extending diode head instead of an emitter head, and an additional piece added to the end of the handle that looked like a small red cap. In this way, much like the Doctor who used it and his TARDIS control room (which, also like the sonic, was primarily of a silver colour scheme, with red highlights), this sonic combined visual elements of both the classic and revived eras of the show, as its casing was more or less shared by all of the classic sonics, and having a light-emitting diode emitter and a kind of pommel at the end of the handle are characteristic of the revived sonics. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')
 
After regenerating at the end of the Last Great Time War, the Doctor kept this model with him during the early adventures of his ninth incarnation. This version was destroyed when the Doctor rigged it to explode in order to seal a rift in interstital space. ([[AUDIO]]: ''[[The Bleeding Heart (audio story)|The Bleeding Heart]]'')
 
=== Uses ===
The [[War Doctor]] often used his sonic screwdriver to summon [[the TARDIS]] to materialise, either around him, ([[AUDIO]]: ''[[The Thousand Worlds (audio story)|The Thousand Worlds]]'')
or nearby. ([[AUDIO]]: ''[[The Heart of the Battle (audio story)|The Heart of the Battle]]'', ''[[A Thing of Guile (audio story)|A Thing of Guile]]'')
 
With it, the Doctor could dismantle an [[Interstitial]]'s [[possibility engine]] by removing its bolts, receive [[homing signal]]s from the TARDIS in the TARDIS Undercroft below the Citadel ([[PROSE]]: ''[[Engines of War (novel)|Engines of War]]'') and activate the [[memory]]-erasing device in the [[Black Archive]]. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')
 
The War Doctor, along with his [[Eleventh Doctor|eleventh]] and [[Tenth Doctor|tenth]] incarnations, used his sonic screwdriver to create a sonic force field to blast back and destroy an attacking Dalek in the [[Time War]]. He also implanted a permanent subroutine within the architecture of the sonic screwdriver's software that would begin the centuries-long calculation to disintegrate a door, as well as continuing a calculation to move [[Gallifrey]] into a [[pocket universe]]. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')
 
His screwdriver was also capable of scanning a [[corpse]] and wiping [[security footage]]. ([[AUDIO]]: ''[[The Bleeding Heart (audio story)|The Bleeding Heart]]'')
 
== The Ninth and Tenth Doctors' sonic screwdriver ==
[[File:Ninth Doctor Good with Teleports.jpg|thumb|The Ninth Doctor's sonic screwdriver. ([[TV]]: ''[[Boom Town (TV story)|Boom Town]]'')]]
After the destruction of his last model, the [[Ninth Doctor]] built himself a new sonic screwdriver. This one had a creamy light grey handle with a "cracked-porcelain" texture matching elements on his TARDIS console and rings around the roundels on the control room walls, silver metal at both the bottom of the handle and the top, and was capped off with a black pommel. Its emitter was blue and sat atop a silver metal section attached to a transparent tube containing black and red wires twisted around each other in the centre that was hidden inside the handle until extended by the slider on the side. The Doctor used this model far more frequently than his previous incarnations had done before. ([[TV]]: ''[[Rose (TV story)|Rose]]'', et al.) The [[Tenth Doctor]] also used this model, as he liked tinkering with technology to make devices he needed.
 
[[File:Human Nature Universal Remote Sonic.JPG|thumb|left|A replacement sonic used by the Tenth Doctor after overloading the former model. ([[TV]]: ''[[Human Nature (TV story)|Human Nature]]'')]]
This version was burnt out by accident after the Tenth Doctor used it to modify an [[X-ray]] output to over 5000%, however, and he replaced it with a similar one with a flatter slider, two yellow wires in the tube instead of the black and red ones, and a greyer handle, ([[TV]]: ''[[Smith and Jones (TV story)|Smith and Jones]]'') though it reverted to its cream handle during his time with Queen Elizabeth ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') and appeared to have a blue handle following his regeneration. ([[TV]]: ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'') The model underwent several changes in colouration, some inadvertent. ([[COMIC]]: ''[[Laundro-Room of Doom (comic story)|Laundro-Room of Doom]]'') This version of the sonic screwdriver was also the first to be shown to have a direct connection to the Doctor's TARDIS ([[TV]]: ''[[Aliens of London (TV story)|Aliens of London]]'') and could be used to override its functions. ([[TV]]: ''[[Utopia (TV story)|Utopia]]'') The Tenth Doctor had this screwdriver on his person during his [[regeneration]], but it was damaged repeatedly afterwards, leading to many malfunctions. Despite the damage, the [[Eleventh Doctor]] used it to overload technology in an attempt to alert the Atraxi to Prisoner Zero's location. This fried it into useless, charred metal, much to his growing annoyance and anger. ([[TV]]: ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'') It was later recovered by [[Charlie Sato]], and taken to [[The Vault (The Scales of Injustice)|the Vault]]. ([[AUDIO]]: ''[[The Turn of the Screw (audio story)|The Turn of the Screw]]'')
 
Multiple versions of these screwdrivers were kept in the [[Twelfth Doctor]]'s [[The Doctor's office (The Pilot)|office]] at [[St Luke's University]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')

== The Eleventh and Twelfth Doctors' sonic screwdriver ==
[[File:ElevenScrewdriverTHE.jpg|thumb|left|The Eleventh Doctor's sonic screwdriver ([[TV]]: ''[[The Hungry Earth (TV story)|The Hungry Earth]]'')]]
After the loss of the previous sonic screwdriver, the TARDIS gifted the Doctor with a new model. Differing radically from the last, with its extendible "claws" and green crystalline emitter resembling the inner structure of the TARDIS's new time rotor, it also had copper plating similar to the new control room. ([[TV]]: ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'') A psychic interface allowed its user to point it at a target and think of the function they wanted. ([[TV]]: ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'', ''[[Death in Heaven (TV story)|Death in Heaven]]'') Having been mentioned to be more than sonic, ([[TV]]: ''[[Night Terrors (TV story)|Night Terrors]]'') this screwdriver also shot beams of green energy in the shape of sonic waves. ([[TV]]: ''[[Day of the Moon (TV story)|Day of the Moon]]'', ''[[Closing Time (TV story)|Closing Time]]'') By at least the time of the Doctor's thirteenth regeneration, it had a voice-activation feature, which the Doctor forgot about when he needed it. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'') It had a charge that could last centuries; it once lasted 300 years before the Doctor could charge it in the TARDIS. ([[TV]]: ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'')
 
Retaining ineffectiveness against [[wood]], it also didn't work against [[Peg Doll]]s ([[TV]]: ''[[Night Terrors (TV story)|Night Terrors]]'') or the [[Wooden King]] and [[Wooden Queen|Queen]]. ([[TV]]: ''[[The Doctor, the Widow and the Wardrobe (TV story)|The Doctor, the Widow and the Wardrobe]]'') The Doctor considered it embarrassing and said that "I need to invent a setting for wood." ([[TV]]: ''[[Night Terrors (TV story)|Night Terrors]]'') In similar situations, he yelled at it in panic; "Aliens made of wood, you know this was always going to happen!", "Yes, I know it's wood. Get over it!" ([[TV]]: ''[[The Doctor, the Widow and the Wardrobe (TV story)|The Doctor, the Widow and the Wardrobe]]'') Though aware of this flaw, he was still able to successfully bluff a [[Wooden Cyberman]] into destroying itself. ([[TV]]: ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'') He also once defended this weakness, saying "Oi! Don't diss the sonic!" ([[TV]]: ''[[The Hungry Earth (TV story)|The Hungry Earth]]'')  At some point it had an anti-freeze setting. ([[TV]]: ''[[The Snowmen (TV story)|The Snowmen]]'') This screwdriver was also shown to have a "red setting", ([[TV]]: ''[[Cold War (TV story)|Cold War]]'') similar to [[River Song's sonic screwdriver|River's sonic screwdriver]].
 
[[File:Sonic and psychic paper.jpeg|thumb|right|The sonic screwdriver and [[psychic paper]] on the TARDIS console. ([[TV]]: ''[[Flatline (TV story)|Flatline]]'')]]
This model was lost and replaced by the Doctor repeatedly, having been bitten in half by a [[sky shark]] and left behind, ([[TV]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'') left with the [[Ganger Doctor]], ([[TV]]: ''[[The Rebel Flesh (TV story)|The Rebel Flesh]]'') destroyed by [[Danny Fisher]] ([[COMIC]]: ''[[The Blood of Azrael (comic story)|The Blood of Azrael]]'') and, in one instance, simply burnt out due to overuse. In the latter instance, a replacement was given to him by [[Santa Claus]]. ([[COMIC]]: ''[[Silent Knight (comic story)|Silent Knight]]'') One of the Twelfth Doctor's sonic screwdrivers was incinerated by the [[Governor (The Blood Cell)|Governor]] when he was admitted into [[the Prison]]. Clara Oswald attempted to give him a new one disguised as a large candle in a birthday cake, but the Governor refused to give the cake to the Doctor. To circumvent this, the Doctor created a [[sonic spoon]] in the interim for the time being. ([[PROSE]]: ''[[The Blood Cell (novel)|The Blood Cell]]'') Ultimately, he left one of his screwdrivers with [[Davros]] after abandoning him as a child. Davros had it in his possession for many years after, until [[Colony Sarff]] returned it to the Doctor. By this point, it was no longer of any real use to him, as it had become heavily damaged and inoperable, visibly weather-beaten from exposure to war and conflict, and with one of the clawed prongs broken off. ([[TV]]: ''[[The Magician's Apprentice (TV story)|The Magician's Apprentice]], [[The Witch's Familiar (TV story)|The Witch's Familiar]]'')
 
The Doctor eventually declared that he was "over" sonic screwdrivers, saying that they "spoil the line of your jacket". He replaced the screwdriver with a pair of [[sonic sunglasses]]. ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'')
 
However, he did not keep this promise, as he used this sonic screwdriver several times afterwards. ([[COMIC]]: ''[[Clara Oswald and the School of Death (comic story)|Clara Oswald and the School of Death]]'', ''[[The Fourth Wall (comic story)|The Fourth Wall]]'')
 
[[File:Tulpa sonic screwdriver.jpg|thumb|left|The Twelfth Doctor's blue version. ([[COMIC]]: ''[[Tulpa (comic story)|Tulpa]]'')]]
When the Eleventh Doctor met the Tenth Doctor in [[England]], [[1562]], upon the latter realising that the former was a future incarnation of himself, they both got out their sonic screwdrivers. The Eleventh Doctor immediately showed off how much bigger his was, to which the Tenth Doctor claimed that his future incarnation was compensating, remarking that "[[regeneration]], it's a [[lottery]]." ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')
 
A version of this screwdriver was kept in the [[Twelfth Doctor]]'s [[The Doctor's office (The Pilot)|office]] at [[St Luke's University]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')
 
At one point during his travels with [[Bill Potts]], the Twelfth Doctor had a version of this sonic design in the colour scheme of his second sonic screwdriver. ([[COMIC]]: ''[[Tulpa (comic story)|Tulpa]]'')

== The Twelfth Doctor's second screwdriver ==
[[File:Twelfth doctor's sonic screwdriver.jpg|thumb|The Doctor tests out his new screwdriver. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')]]
After spending a period of time using a combination of [[sonic sunglasses]] and his green-emitter sonic screwdriver, ([[COMIC]]: ''[[Clara Oswald and the School of Death (comic story)|Clara Oswald and the School of Death]]'') the Twelfth Doctor was gifted a new model by the TARDIS.
 
While one account showed him gaining it after he had found [[Gallifrey]] at the [[end of the universe]], ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'') another account depicted him using it whilst travelling with [[Clara Oswald]]. ([[COMIC]]: ''[[The Day at the Doctors (comic story)|The Day at the Doctors]]'')
 
This new model had a very mechanical and complicated-looking, TARDIS blue, metal handle with multiple emitters, once again resembling the inner structure of the [[time rotor]] itself. The emitter was once again blue in colour, and the ring of emitters could all light up in a circling motion when activated. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'') He continued to use his sonic sunglasses as well, thus giving him two choices of sonic instruments. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'', ''[[Extremis (TV story)|Extremis]]'')
 
This screwdriver could glow blue ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]''), red ([[COMIC]]: ''[[Robo Rampage (comic story)|Robo Rampage]]''), or green. ([[COMIC]]: ''[[Gallery (comic story)|Gallery]]'', [[TV]]: ''[[For Tonight We Might Die (TV story)|For Tonight We Might Die]]'') It was still ineffectual against [[wood]]. ([[TV]]: ''[[Empress of Mars (TV story)|Empress of Mars]]'')
 
The Doctor sometimes attached this screwdriver to his guitar so that he could use both at the same time. ([[COMIC]]: ''[[The Pestilent Heart (comic story)|The Pestilent Heart]]'')
 
When the Doctor was stuck in [[1972]], the screwdriver "ran out of juice" and the Doctor was unable to charge it because he was without his TARDIS. ([[COMIC]]: ''[[Moving In (comic story)|Moving In]]'')
 
After regenerating into the [[Thirteenth Doctor]], the TARDIS console room exploded due to the damage it took from the intensity of the regeneration energy. The Doctor was thrown out of the TARDIS from the explosion, causing her to free fall to the Earth's surface. ([[TV]]: ''[[Twice Upon a Time (TV story)|Twice Upon a Time]]'') As she fell, she lost this sonic screwdriver along with everything else in her pockets. ([[TV]]: ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'')

== The Thirteenth Doctor's sonic screwdriver ==
[[File:Sonic-3.jpg|thumb|The [[Thirteenth Doctor]]'s newly created sonic. ([[TV]]: ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'')]]
Due to losing everything in her [[pocket]]s following her [[regeneration]] and fall, the [[Thirteenth Doctor]] lost [[Twelfth Doctor|her previous incarnation's]] sonic screwdriver (and sonic sunglasses). As a result, the Doctor chose to build one of her own in a workshop in [[Sheffield]]. This one was far simpler in appearance than the last screwdriver with a simple steel body, and a crystal on the tip that glowed [[Amber (colour)|amber]] while in use, taken from a [[Stenza]] [[Tim Shaw's pod|transport chamber]]. ([[TV]]: ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'')
 
It was unique from previous sonic screwdrivers in the fact that design-wise the handle was now the unique part of the sonic{{what}}, as opposed to the emitter, ([[TV]]: ''[[The Woman Who Fell to Earth (TV story)|The Woman who Fell to Earth]]'') which had previously either had interchangeable heads, ([[TV]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'' - ''[[The Visitation (TV story)|The Visitation]]'') an extendable emitter, ([[TV]]: ''[[Smith and Jones (TV story)|Smith and Jones]]'' - ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'') "claws" deployed when the sonic was activated, ([[TV]]: ''[[The Eleventh Hour (TV story)|The Eleventh Hour]] ''- ''[[Last Christmas (TV story)|Last Christmas]]'') or a large emitter glowing in a rotating fashion. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'' - ''[[Twice Upon a Time (TV story)|Twice Upon a Time]]'') It was also the first of the Doctor's sonic devices to have a curved handle, allowing for a more natural grip.
 
Comparing it to a [[Swiss Army knife]], but without the knife, the Doctor explained that it functioned not only as a [[screwdriver]], but as a [[scanner]] and a [[tin opener]], and it could be used for diagnostics. ([[TV]]: ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'')
 
It had a self-rebooting feature, allowing it to restore power if drained. ([[TV]]: ''[[The Tsuranga Conundrum (TV story)|The Tsuranga Conundrum]]'') It could not work on machinery if the power cells were fluctuating. ([[TV]]: ''[[Kerblam! (TV story)|Kerblam!]]'')
 
When a [[Thijarian remnant]] sample overloaded the sonic, for having too many inputs, the Doctor noted that this had never happened before. This was because of the immeasurably high [[density]] of this substance, containing the remains of [[Thijar]] and all their ancestors. ([[TV]]: ''[[Demons of the Punjab (TV story)|Demons of the Punjab]]'') On another occasion, the sonic could calculate such an impossible density, but that "density [blew its] mind". ([[TV]]: ''[[The Battle of Ranskoor Av Kolos (TV story)|The Battle of Ranskoor Av Kolos]]'')
 
To the Doctor's extreme surprise, her sonic could be rendered inoperative by [[recon scout]] [[Dalek]]s. ([[TV]]: ''[[Resolution (TV story)|Resolution]]'')

== Behind the scenes ==
=== The sonic screwdriver prop ===
* In [[Victor Pemberton]]'s script for ''[[Fury from the Deep (TV story)|Fury from the Deep]]'', it was simply described as the Doctor's "own version of a screwdriver". When seeing a normal screwdriver in rehearsals, production assistant [[Michael Briant]] suggested using another prop and the device having sonicwaves, [[Patrick Troughton]] then took a penlight from the [[visual effects]] department. ([[DWM 277]])
* While shooting, ''[[Fury from the Deep (TV story)|Fury from the Deep]]'', Troughton accidentally lost the original prop and it had to be replaced at the last minute by [[Peter Day]]<ref>https://twitter.com/NothingLane/status/909107817830895616 Extract] of [[Peter Day]]'s interview by [[Richard Bignell]] for [[Loose Cannon Productions]]' ''Doctor Who - The Making of Fury from the Deep''</ref> with the safety whistle<ref name="2ndEssay">[https://thezeroroomblog.blogspot.com/2019/01/the-2nd-doctors-sonic-screwdrivers.html Essay] by [[Lee Moone]]</ref> of [[Deborah Watling]]'s life jacket outfit.<ref>[https://www.therpf.com/forums/threads/2-sonics-for-the-2nd-doctor.179221/page-6#post-3227683 Account report] of [[Frazer Hines]]</ref>
* In Episode 6 of ''[[Fury from the Deep (TV story)|Fury from the Deep]]'', the Second Doctor uses one of his devices together with some [[amplifier]]s to produce a "sonic laser soundwave" but it is unknown if this is the sonic screwdriver, and if so whether it was the retrieved original prop or not. The combined props are seen in a surviving alternate take of the climax battle of the episode, in which a sort of medical hammer appears to be lodged in the amplifier and manipulated by Troughton.
* The Second Doctor's slim penlight prop from ''[[The War Games (TV story)|The War Games]]'' has been identified as a Eveready model no. 1980 (1968-70 version).<ref name="2ndEssay" />
* The Third Doctor's sonic screwdriver is a modified prop from the [[Gerry Anderson]] film ''Thunderbirds Are Go'', where it appeared as a screwdriver of the non-sonic variety. When [[Century 21 Productions]] was closed, the prop, among others, was sold off to the BBC.<ref>[https://securityhazard.wordpress.com/2017/04/21/thunderbirds-are-go-1966/ Movie analysis]</ref>
* The sonic screwdriver was [[retire]]d during the [[Fifth Doctor]] serial ''[[The Visitation (TV story)|The Visitation]]'', as it was felt that it had been overused. It was absent for the [[Sixth Doctor|Sixth]] and [[Seventh Doctor]]'s eras, except in [[Doctor Who (TV story)|the TV Movie]], in which the Seventh Doctor used it to lock [[the Master]]'s remains away. The [[Eighth Doctor]] recovered it at the end of the film. After appearing in many Seventh and Eighth Doctor audio adventures from [[Big Finish Productions]], the tool was reintroduced with the [[Ninth Doctor]] and has become the show's most frequently used gadget besides [[the TARDIS]] itself.
* The screwdriver was given a rest once more in [[Series 9 (Doctor Who)|series 9]], only appearing in ''[[The Magician's Apprentice (TV story)|The Magician's Apprentice]]'', and a new version was introduced in the last episode ''[[Hell Bent (TV story)|Hell Bent]]''. It was replaced by [[sonic sunglasses]] for that entire season.
* For unexplained reasons, the [[Tenth Doctor]]'s sonic screwdriver had a green casing in ''[[The Infinite Quest (TV story)|The Infinite Quest]]''.
* There are two main versions of the Tenth Doctor's sonic screwdriver — one which has a slide feature with button, and one which does not slide and has a fixed button. The two prop types varied each episode.
* The War Doctor's sonic screwdriver prop was created by modifying a Fourth Doctor's sonic screwdriver replica toy.
* When the Doctor handles the screwdriver, the clinking noises produced (when he throws and catches it) are created by repeating the motions with a corkscrew, the handles of which bump against the casing to produce the required noise. These noises are dubbed over the footage.
 
=== Concept art ===
* Early conceptual art of the first modern era sonic screwdriver features a different "tube" section. Notes refer to "glowing organic circuitry" and a movable ball-joint on the emitter to allow use around corners and in tight spaces. Instead of the "glowing circuitry," the actual prop and toy reproductions featured a black "swivel" like a simple helix. When given a personal copy of the concept art, [[David Tennant]] himself commented on the lack of the swivelling emitter. {{Source}}
* Another early piece of concept art, similar to a simple Bitmap drawing, reveals that the black "cap" at the reverse end of the sonic screwdriver was intended to be an opening set of "feet," allowing the sonic screwdriver to plug into a section of the [[TARDIS console]]. This feature was also dropped from the eventual prop model. {{source}}
* [[Dan Walker]] redesigned the sonic screwdriver, devising how it looks when used by the Ninth and Tenth Doctors. "We hit upon the idea of spark plugs, which in themselves are very iconic," Walker stated. "Initially, we started off quite techy, with retractable elements that would interface with an unlimited number of devices." Despite his work on redesigning the device, Walker wasn't allowed to take one of the sonic screwdriver props home with him. (''ImageFX'' magazine, October 2008, pp. 63 & 64)
 
=== Sonic screwdriver toy ===
* A toy of the [[Eleventh Doctor]]'s version was seen in "Light Echoes", an edition of [http://www.bbc.co.uk/programmes/b006mk7h "The Sky at Night"] broadcast on [http://www.bbc.co.uk/bbc4 BBC4] on Wednesday 5th October 2010. The screwdriver was (jokingly) used to scan a part of the [http://www.lofar.org.uk LOFAR] radio telescope, then under construction in Chilbolton, Hampshire, UK.
* The Eleventh Doctor's sonic screwdriver toy has a total of four sound effects, two of which alternate with every other button press. The third is activated by pressing twice and holding on the third button push. The fourth is activated with three presses and a hold on the fourth push. However, in some models of the toy, over-use of the hidden sound effects causes the sound functions to eventually break, leaving only the LED functional.
* The customiseable toy sonic screwdriver set featuring three screwdrivers with interchangeable parts can produce up to eight sound effects: the first two are the basic screwdriver sound, with slightly different pitches, and alternate each time the button is pressed. The other six effects are achieved in a similar manner to those of the Eleventh Doctor's sonic screwdriver toy, and are accompanied by a flashing lights instead of a constant light.
* Since the War Doctor's sonic screwdriver prop was created by modifying a toy replica, the toy version that was subsequently produced is screen accurate.
 
=== ''Attack of the Graske'' ===
* In [[NOTVALID]]: ''[[Attack of the Graske (video game)|Attack of the Graske]]'', the [[Tenth Doctor]] appears to break the [[fourth wall]] by noting the player at home's been watching his adventures. Later, he points the sonic screwdriver at the television screen, transferring its powers to the player's digital remote control. This, along with having the player choose multiple endings to this game, disqualifies it as a [[valid source]] on this wiki.
 
=== Other matters ===
* In the animated [[title sequence]] of the [[Series 1 (Totally Doctor Who)|first series]] of ''[[Totally Doctor Who]]'', the [[Tenth Doctor]] uses his sonic screwdriver to fire a blue burst of energy which blows off the [[hand]] of a [[Cyberman]].
* In the original script for ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'', the Doctor referred to his screwdriver as "Level 4000" technology.
* Scientists at the University of Dundee invented a device which turns objects with ultrasonic waves, an invention which has been described as a real-world version of the Doctor's sonic screwdriver.<ref>[http://www.bbc.co.uk/news/uk-scotland-17760077 Dr Who's sonic screwdriver 'invented' at Dundee University]</ref>
* ''[[Legacy (video game)|Doctor Who: Legacy]]'' mobile game contains a premium pack called "Sonic Adventure", which is centred around finding various sonic devices used by different incarnations of the Doctor and by several other characters. The playable characters form this premium pack represented almost every model of sonic screwdriver encountered in the DWU.
