The '''sonic screwdriver''', also called a '''[[sonic probe]]''' or simply "the '''sonic'''", was a highly versatile [[tool]] used by many people throughout the universe, the most prominent of them being [[the Doctor]].


The '''sonic screwdriver''', also called a '''[[sonic probe]]''' or simply the '''sonic''', was a highly versatile tool used by [[the Doctor]]. He modified and ostensibly upgraded it over the years, giving it an increasing number of applications.  Early versions were used mainly for the picking of locks and for projecting sound so as to, for example, detonate objects and fry circuitry.  By the time of the [[Ninth Doctor]], the sonic was able to also be used as a sophisticated scanning device, with medical applications. Subsequent incarnations gave it even wider functionality, such as the ability to hack into computers, provide geolocation and actively defend against some types of assault weapons by frying their internal mechanics and causing the weapons to burst into flames and spark from the inside. The tool seemed to have electromagnetic properties and abilities, as it could be used to electrify the nervous system, and could create powerful frequencies and signals, as well as use sound to carry out its functions, even to the point where three of its latest incarnations where able to create a sonic force blast while working together or shoot green sonic energy waves.
While almost always referred to as a sonic screwdriver, this device has on occasion been referred to as a sonic probe by people other than the Doctor, such as [[Dalek Sec]] ([[TV]]: {{cs|Doomsday (TV story)}}) and a version of [[Amy Pond]] who had been stuck on [[Apalapucia]] for 36 years. ([[TV]]: {{cs|The Girl Who Waited (TV story)}}) The [[Tenth Doctor|Tenth]] ([[TV]]: {{cs|Doomsday (TV story)}}) and [[Eleventh Doctor|Eleventh]] ([[TV]]: {{cs|The Girl Who Waited (TV story)}}) Doctors openly disliked this and corrected those who did so. The [[Ninth Doctor|Ninth]] ([[TV]]: {{cs|The Doctor Dances (TV story)}}) and [[Twelfth Doctor]]s ([[TV]]: {{cs|The Husbands of River Song (TV story)}}) also defended when others claimed it was inferior to other sonic devices like a [[sonic blaster]] or [[sonic trowel]].
 
All of these [[incarnation]]s utilised the same software, though they used different cases. For all intents and purposes, the [[War Doctor]]'s sonic was the same as the [[Eleventh Doctor]]'s some 400 years later. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')

== Technology and functions ==
The sonic screwdriver was considered to be very advanced [[Gallifrey]]an technology. ([[PROSE]]: ''[[Heart of TARDIS]]'')
Identified by the [[Dalek]]s as a "[[sonic probe]]", ([[TV]]: {{cs|Doomsday (TV story)}}) the sonic screwdriver was considered to be very advanced [[Gallifrey]]an technology, ([[PROSE]]: {{cs|Heart of TARDIS (novel)}}) although the Doctor could make one by using resources found on [[21st century]] [[Earth]] with help from [[Stenza]] technology. ([[TV]]: {{cs|The Woman Who Fell to Earth (TV story)}}) During the [[Dalek-Movellan War]], [[Davros]] dismissed the sonic screwdriver as a "simple" tool. ([[AUDIO]]: {{cs|The Triumph of Davros (audio story)}})
 
[[The Doctor]] claimed that he either invented or designed the specific sonic screwdriver which he owned. When [[Kazran Sardick]] was confused as to what to do when it looked like [[Abigail Pettigrew]] was about to kiss him, the [[Eleventh Doctor]] told Kazran to trust him and kiss Abigail, as "It's this, or go to your room and design a new kind of screwdriver. Don't make my mistakes. Now, go." ([[TV]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'') When Captain [[Jack Harkness]] asked the [[Ninth Doctor]], "Who looks at a screwdriver and thinks 'Ooh, this could be a little more sonic'?", the [[Ninth Doctor]] responded, "What? You never been bored? Never had a long night? Never had a lot of [[cabinet]]s to put up?" ([[TV]]: ''[[The Doctor Dances (TV story)|The Doctor Dances]]'') Other individuals had similar devices, such as the [[sonic pen]] used by [[Cofelia|Miss Foster]] ([[TV]]: ''[[Partners in Crime (TV story)|Partners in Crime]]'') and the [[sonic blaster]] used first by Captain [[Jack Harkness]] ([[TV]]: ''[[The Empty Child (TV story)|The Empty Child]]'' / ''[[The Doctor Dances (TV story)|The Doctor Dances]]'') and later [[River Song]]. ([[TV]]: ''[[Silence in the Library (TV story)|Silence in the Library]]'' / ''[[Forest of the Dead (TV story)|Forest of the Dead]]'') [[Sarah Jane Smith]] had her [[sonic lipstick]], ([[TV]]: ''[[Invasion of the Bane]]'', et. al.) and the Doctor himself once used a [[sonic cane]]. ([[TV]]: ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'')
 
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]]'') There were also electrical components. ([[COMIC]]: ''[[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]]'') and used 34-H to sink a ship. ([[COMIC]]: ''[[Second Wave]]'') It had a setting 85 that undid security codes to unlock doors. ([[TV]]: ''[[The Lazarus Experiment]]'') The [[Ninth Doctor]] told Rose to use setting 2428D to re-attach [[barbed wire]]. ([[TV]]: ''[[The Doctor Dances]]'') Sarah Jane used the Theta Omega setting to melt plastic vines. ([[TV]]: ''[[The Android Invasion (TV story)|The Android Invasion]]'') The [[Twelfth Doctor]] told [[Clara Oswald|Clara]] to use setting number 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 sixty-one 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]]: ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'', ''[[Death in Heaven (TV story)|Death in Heaven]]'')
 
The different versions of the Doctor's sonic screwdrivers exhibited different capabilities and uses, such as the interception of signals ranging from transmat beams to conscious thought; ([[TV]]: ''[[The End of the World (TV story)|The End of the World]]'') medical diagnostics ([[TV]]: ''[[The Empty Child]]'') and repair of organic parts; ([[TV]]: ''[[The Vampires of Venice]]'') cutting, but also re-attaching materials such as barbed wire; ([[TV]]: ''[[The Doctor Dances]]'') operating Earth machinery such as computers ([[TV]]: ''[[School Reunion]]'') and even cash machines (at regular and high eject speeds); ([[TV]]: ''[[The Runaway Bride]]'') creating a spark to light a candle ([[TV]]: ''[[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 locks; ([[TV]]: ''[[The Rings of Akhaten (TV story)|The Rings of Akhaten]]'') and, on the rare occasion, driving screws without touching them. ([[TV]]: ''[[The War Games]]'', ''[[The Ark in Space]]'', ''[[The Doctor's Wife (TV story)|The Doctor's Wife]]'')
 
Although it was primarily a tool, the sonic screwdriver could also be used as a defensive weapon. The Tenth Doctor put it in a sound board to destroy the [[Robot Santa]]s by overloading their sensors. ([[TV]]: ''[[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]]'') 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 Doctor also used it to try and help River Song defeat a group of [[Silent]]s although River teased him by saying it would be better if he used it to "build a cabinet". However, the Doctor implied that although it couldn't actually hurt the Silents it could weaken the power of their electricity, therefore allowing him to provide River with a certain degree of protection while she shot down their foes. ([[TV]]: ''[[Day of the Moon (TV story)|Day of the Moon]]'')
 
Although the [[Eighth Doctor]] once claimed the device could destroy a Dalek's brain if held directly against the casing when activated, ([[PROSE]]: ''[[War of the Daleks]]'') according to the Tenth Doctor, the device could not be used to wound, maim or kill living things. ([[TV]]: ''[[Doomsday]]'', ''[[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 End of the World (TV story)|The End of the World]]'', ''[[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]]'')
 
From time to time, the sonic screwdriver needed to be recharged. ([[TV]]: ''[[Silence in the Library]]'' / ''[[Forest of the Dead]]'', [[PROSE]]: ''[[The Monsters Inside]]'', [[COMIC]]: ''[[Bizarre Zero]]'') It was self-repairing and could send out a homing signal to any parts that had been separated. ([[TV]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'') However, it was up to the owner to collect the parts for reassembly.
 
Sonic screwdrivers and similar technology could not unlock a [[deadlock seal]]. ([[TV]]: ''[[School Reunion]]'', ''[[The Night of the Doctor]]'') However, Miss Foster's [[sonic pen]] could open the deadlock seals that it was programmed to within her own facility when the Doctor's screwdriver could not. ([[TV]]: ''[[Partners in Crime]]'') Some or all versions were ineffective against [[wood]], or in the presence of some models of [[hairdryer]]s. ([[TV]]: ''[[Silence in the Library]]'' / ''[[Forest of the Dead]]'', ''[[The Hungry Earth]]'', ''[[Night Terrors]]'', ''[[The Time of the Doctor]]'', [[PROSE]]: ''[[Catastrophea (novel)|Catastrophea]]'')
 
During his lifetime as the Twelfth Doctor, the Time Lord claimed to have abandoned sonic screwdrivers in favor of wearable technology like his [[sonic sunglasses]]. ([[TV]]: ''[[Under the Lake]]'') However, after returning to [[Gallifrey]] and departing again, 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 to use a sonic screwdriver, the Doctor accepted the TARDIS's gift. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')
 
== Variants of the Doctor's sonic screwdriver ==
[[File:Doc2Sonic.jpg|thumb|right|The earliest version of the sonic screwdriver in use. ([[TV]]: ''[[The War Games (TV story)|The War Games]]'')]]
=== The First and Second Doctors' sonic ===
One sonic screwdriver, a small, simple [[metal]] rod similar to a penlight, was used by the [[First Doctor|First]] ([[PROSE]]: ''[[Venusian Lullaby (novel)|Venusian Lullaby]]'') and [[Second Doctor|Second]] ([[TV]]: ''[[Fury from the Deep (TV story)|Fury from the Deep]]'') Doctors. It was also used by the [[Eighth Doctor]] after being destroyed "centuries ago", with the Doctor claiming to his [[companion]] [[Samantha 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]]'')
 
The Eighth Doctor carried a similar model near the end of his life. Cylindrical and [[silver]], with a [[blue]] emitter diode tip, he used it in a surgical procedure to scan his patient and to seal incisions. 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]]'')

=== The Third, Fourth and Fifth Doctors' sonic ===
[[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 active 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]]'')
 
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. ([[TV]]: ''[[Frontier in Space (TV story)|Frontier in Space]]'')
 
[[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]]'', ''[[Castrovalva (TV story)|Castrovalva]]'') It was ultimately destroyed when a [[Terileptil]] leader forced the [[Fifth Doctor]] to drop the screwdriver inside a holding cell, then incinerated it with 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 [[Seventh Doctor|his seventh incarnation]]. ([[AUDIO]]: ''[[Persuasion (audio story)|Persuasion]]'')

=== The Seventh and Eighth Doctors' sonic ===
{{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]]'' et al.) 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 [[the Monk]], ([[PROSE]]: ''[[No Future (novel)|No Future]]'') and that he received it as compensation after suing the Terileptils for [[criminal]] damage. ([[PROSE]]: ''[[GodEngine (novel)|GodEngine]]'')
 
This model 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]]'') Once, while suffering from amnesia, the 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]] 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'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]]'')

=== The War Doctor's sonic ===
[[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]]'')]]
By the end of his life, the [[War Doctor]] used a sonic screwdriver with a simple metallic handle and a red diode at the end. It appeared to be a further upgraded version of the Eighth Doctor's first sonic screwdriver, adapted for battle, 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. ([[TV]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'')

=== The Ninth and Tenth Doctors' sonic ===
[[File:Ninth Doctor Good with Teleports.jpg|thumb|The Ninth Doctor's sonic screwdriver. ([[TV]]: ''[[Boom Town (TV story)|Boom Town]]'')]]
By his ninth incarnation, the Doctor possessed yet another sonic screwdriver model. This one had a cream handle with a "cracked-porcelain" texture, silver metal at both the handle and the tip and was capped off with a black pommel. This model was carried by the [[Ninth Doctor]], who used it far more frequently than his previous incarnations had done before. ([[TV]]: ''[[Rose (TV story)|Rose]]'') 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%, but he replaced it with a similar model with a light grey handle, ([[TV]]: ''[[Smith and Jones (TV story)|Smith and Jones]]'') though it reverted back 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 shape{{fact}} and 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]]'')

=== The Eleventh and Twelfth Doctors' sonic ===
[[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]]'') Oddly, he defended once, 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'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]]'') 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. He created a [[sonic spoon]] in the interim. ([[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 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]]'')

===== Amplification =====
When [[Kazran Sardick]] was confused as to what to do when it looked like [[Abigail Pettigrew]] was about to [[kissing|kiss]] him, the [[Eleventh Doctor]] told Kazran to trust him and kiss Abigail, as "it's this, or go to your room and design a new kind of screwdriver. Don't make my mistakes." ([[TV]]: {{cs|A Christmas Carol (TV story)}}) When Captain [[Jack Harkness]] asked the [[Ninth Doctor]], "Who looks at a screwdriver and thinks 'Ooh, this could be a little more sonic'?", the Doctor defensively responded, "What?

=== The Twelfth Doctor's second screwdriver ===
From time to time, the sonic screwdriver needed to be recharged. ([[PROSE]]: {{cs|The Monsters Inside (novel)}}, [[COMIC]]: {{cs|Bizarre Zero (comic story)}}) It was self-repairing and could send out a homing signal to any parts that had been separated. ([[TV]]: {{cs|A Christmas Carol (TV story)}}) One account held that a sonic screwdriver was powered by a type of [[crystal]] that was similar to the [[Metebelis crystal]]s. ([[COMIC]]: {{cs|The Forgotten (comic story)}})
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]]'')
Sonic screwdrivers and similar technology could not unlock a [[deadlock seal]]. ([[TV]]: {{cs|School Reunion (TV story)}}, {{cs|The Night of the Doctor (TV story)}}) However, Miss Foster's sonic pen could open the deadlock seals that it was programmed to within her own facility when the Doctor's screwdriver could not. ([[TV]]: {{cs|Partners in Crime (TV story)}}) It also couldn't unlock the doors to the TARDIS if they had been manually locked at the console. ([[TV]]: {{cs|Utopia (TV story)}}) Some or all versions were ineffective against [[wood]]. ([[TV]]: {{cs|Night Terrors (TV story)}}, {{cs|The Doctor, the Widow and the Wardrobe (TV story)}}, {{cs|The Time of the Doctor (TV story)}}, {{cs|Empress of Mars (TV story)}}) It didn't work in the presence of some models of [[hairdryer]]s, although the Tenth Doctor stated he was working on it. ([[TV]]: {{cs|Forest of the Dead (TV story)}}, [[PROSE]]: {{cs|Catastrophea (novel)}})


This new model had a 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 all lit 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]]'')  
== Individual sonic screwdrivers ==
=== The Doctor's screwdriver ===
{{Main|The Doctor's sonic screwdriver}}
[[The Doctor]], throughout many of their lives, possessed a sonic screwdriver. They originally used [[Second Doctor's sonic screwdriver|a basic model]] in their [[First Doctor|first]] ([[PROSE]]: {{cs|Venusian Lullaby (novel)}}) and [[Second Doctor|second incarnations]], ([[TV]]: {{cs|Fury from the Deep (TV story)}}) before [[Third Doctor's sonic screwdriver|upgrading]] in [[Third Doctor|their third]]. ([[TV]]: {{cs|The Sea Devils (TV story)}}) However, according to one account, the First Doctor was unfamiliar with the sonic screwdriver when he met the [[Twelfth Doctor]]. ([[TV]]: {{cs|Twice Upon a Time (TV story)}}) Similarly, the accounts depicting the Doctor's life as the Timeless Child prior to their first incarnation showed at least one of them as being unfamiliar with the sonic screwdriver and dismissive of it. ([[TV]]: {{cs|Fugitive of the Judoon (TV story)}}) The Doctor continued to use the model introduced during his third incarnation until it was destroyed in [[Fifth Doctor|their fifth]] by a [[Terileptil]] leader. ([[TV]]: {{cs|The Visitation (TV story)}}) It wasn't until they were in their [[Seventh Doctor|seventh incarnation]] before they began to use [[Seventh Doctor's sonic screwdriver|a screwdriver]] again, taking on various different models throughout the years. ([[TV]]: {{cs|Doctor Who (TV story)}}, {{cs|Rose (TV story)}}, {{cs|The Eleventh Hour (TV story)}}, {{cs|Hell Bent (TV story)}}, {{cs|The Woman Who Fell to Earth (TV story)}}, [[WC]]: {{cs|The Fourteenth Doctor's Sonic Screwdriver (webcast)}}, [[AUDIO]]: {{cs|The World Tree (audio story)}})


While it usually emitted a blue light, this screwdriver could also glow red ([[COMIC]]: ''[[Robo Rampage (comic story)|Robo Rampage]]'') or green. ([[COMIC]]: ''[[Gallery (comic story)|Gallery]]'')
[[File:Jeremy Enecio 3rd Doctor cropped.jpg|thumb|left|The [[Third Doctor]] wields an early model of [[the Doctor's sonic screwdriver]]. ([[GRAPHIC]]: {{cs|Doctor Who Evergreen (illustration)}})]]
Early versions of their sonic screwdriver were used mainly for the [[lock picking|picking]] of [[lock]]s and for projecting [[sound]] so as to, for example, [[explosion|detonate]] objects and fry [[circuit]]ry. ([[TV]]: {{cs|The Sea Devils (TV story)}}) By the time of the [[Ninth Doctor]], the sonic was able to also be used as a sophisticated [[scanner|scanning]] device, with [[medicine|medical]] applications. ([[TV]]: {{cs|The Empty Child (TV story)}}) Subsequent incarnations gave it even wider functionality, such as the ability to [[hacking|hack]] into [[computer]]s, ([[TV]]: {{cs|Smith and Jones (TV story)}}) provide [[geolocation]] ([[TV]]: {{cs|Evolution of the Daleks (TV story)}}) and actively defend against some types of assault [[weapon]]s by frying their internal mechanics and causing the weapons to burst into flames and spark from the inside. ([[TV]]: {{cs|Cold Blood (TV story)}}) The tool could create powerful frequencies and signals, ([[TV]]: {{cs|Partners in Crime (TV story)}}, {{cs|Thin Ice (TV story)}}) as well as use sound to carry out its functions, even to the point where three of its latest incarnations where able to create a [[sonic blast|sonic force blast]] powerful enough to repel and destroy a [[Dalek]] while working together, ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) as well as shoot green sonic energy waves to briefly incapacitate or stun a target. ([[TV]]: {{cs|The Doctor Falls (TV story)}})


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]]'')
All of these [[incarnation]]s utilised the same core [[software]], though they used different [[hardware]]. While it was different individual model, for all intents and purposes the [[War Doctor]]'s sonic was the same as the [[Eleventh Doctor]]'s some 400 years later. ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) However, the [[Thirteenth Doctor]], having lost the Twelfth Doctor's sonic screwdriver, created her own version. As such, hers used unique software, and was made from 21st century Earth components, as well as part of a Recall Circuit from the Stenza Homeworld. ([[TV]]: {{cs|The Woman Who Fell to Earth (TV story)}}) Although, by the time of the [[Fifteenth Doctor]], [[Fifteenth Doctor's sonic screwdriver|his screwdriver]] featured the same software as previous models. ([[AUDIO]]: {{cs|The World Tree (audio story)}})

The Twelfth Doctor gave [[River Song]] another screwdriver before River's final date with him at the [[Singing Towers]] of [[Darillium]]. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'') This version of the sonic screwdriver had the settings of the [[Tenth Doctor]]'s model when he met her at [[the Library]], along with "dampers" and a "red setting" that allowed it to work without interference from [[Doctor Moon]]. The Doctor gave it to River so she would be ready when she met his tenth incarnation in [[the Library]]. ([[TV]]: ''[[Forest of the Dead (TV story)|Forest of the Dead]]'') It was the first gift the Twelfth Doctor personally gave to River face-to-face, after seeing that she was using a [[sonic trowel]], which he found "embarrassing".

=== The sonic screwdriver prop ===
According to the fiction source [[REF]]: ''[[Doctor Who: The Visual Dictionary]]'', a sonic screwdriver was a common and basic [[Time Lord]] device. If needed, a Time Lord could make one from scratch in very little time.
* The sonic screwdriver was [[retire]]d during the [[Fifth Doctor]] serial ''[[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.
* For unexplained reasons, the [[Tenth Doctor]]'s sonic screwdriver had a green casing in ''[[The Infinite Quest]]''.
* During early production of [[Series 1 (Doctor Who)|Series 1]] (2005), the production crew decided to switch from their original prop to one based on the toy sonic screwdriver because the first prop was prone to falling apart. The production team secured moulds of the toy replica to make a more reliable prop for [[Series 2 (Doctor Who)|the next season]].
* 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 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.
* 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.
 
=== 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.
 
=== ''The Visual Dictionary'' ===
* According to the non-fiction source [[REF]]: ''[[Doctor Who: The Visual Dictionary]]'' (which this wiki does not count as a [[valid source]]) the sonic screwdriver was a common and basic [[Time Lord]] device. If needed, a Time Lord could make one from scratch in very little time.
 
=== ''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 original script for ''[[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>

Sonic screwdriver
Appearances
You may be looking for the mobile app.

The sonic screwdriver, also called a sonic probe or simply "the sonic", was a highly versatile tool used by many people throughout the universe, the most prominent of them being the Doctor.

While almost always referred to as a sonic screwdriver, this device has on occasion been referred to as a sonic probe by people other than the Doctor, such as Dalek Sec (TV: Doomsday [+]Loading...["Doomsday (TV story)"]) and a version of Amy Pond who had been stuck on Apalapucia for 36 years. (TV: The Girl Who Waited [+]Loading...["The Girl Who Waited (TV story)"]) The Tenth (TV: Doomsday [+]Loading...["Doomsday (TV story)"]) and Eleventh (TV: The Girl Who Waited [+]Loading...["The Girl Who Waited (TV story)"]) Doctors openly disliked this and corrected those who did so. The Ninth (TV: The Doctor Dances [+]Loading...["The Doctor Dances (TV story)"]) and Twelfth Doctors (TV: The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"]) also defended when others claimed it was inferior to other sonic devices like a sonic blaster or sonic trowel.

Technology and functions[[edit] | [edit source]]

Identified by the Daleks as a "sonic probe", (TV: Doomsday [+]Loading...["Doomsday (TV story)"]) the sonic screwdriver was considered to be very advanced Gallifreyan technology, (PROSE: Heart of TARDIS [+]Loading...["Heart of TARDIS (novel)"]) although the Doctor could make one by using resources found on 21st century Earth with help from Stenza technology. (TV: The Woman Who Fell to Earth [+]Loading...["The Woman Who Fell to Earth (TV story)"]) During the Dalek-Movellan War, Davros dismissed the sonic screwdriver as a "simple" tool. (AUDIO: The Triumph of Davros [+]Loading...["The Triumph of Davros (audio story)"])

The Doctor claimed to have either invented or designed the specific sonic screwdriver which they owned. In fact, the Seventh Doctor claimed to have filed a patent on the technology, (AUDIO: The Unknown [+]Loading...["The Unknown (audio story)"]) and to have copyright on the design. (AUDIO: The Quantum Possibility Engine [+]Loading...["The Quantum Possibility Engine (audio story)"])

When Kazran Sardick was confused as to what to do when it looked like Abigail Pettigrew was about to kiss him, the Eleventh Doctor told Kazran to trust him and kiss Abigail, as "it's this, or go to your room and design a new kind of screwdriver. Don't make my mistakes." (TV: A Christmas Carol [+]Loading...["A Christmas Carol (TV story)"]) When Captain Jack Harkness asked the Ninth Doctor, "Who looks at a screwdriver and thinks 'Ooh, this could be a little more sonic'?", the Doctor defensively responded, "What? You never been bored? Never had a long night? Never had a lot of cabinets to put up?" (TV: The Doctor Dances [+]Loading...["The Doctor Dances (TV story)"])

Other individuals had similar devices, such as the sonic pen (which appeared to serve a near-identical function) used by Miss Foster (TV: Partners in Crime [+]Loading...["Partners in Crime (TV story)"]) and the sonic blaster used first by Captain Jack Harkness (TV: The Empty Child [+]Loading...["The Empty Child (TV story)"] / The Doctor Dances [+]Loading...["The Doctor Dances (TV story)"]) and later River Song. (TV: Silence in the Library [+]Loading...["Silence in the Library (TV story)"] / Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"]) Sarah Jane Smith had her sonic lipstick, (TV: Invasion of the Bane [+]Loading...["Invasion of the Bane (TV story)"], etc.) and the Doctor himself once used a sonic cane.

(TV: The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"])

From time to time, the sonic screwdriver needed to be recharged. (PROSE: The Monsters Inside [+]Loading...["The Monsters Inside (novel)"], COMIC: Bizarre Zero [+]Loading...["Bizarre Zero (comic story)"]) It was self-repairing and could send out a homing signal to any parts that had been separated.

Individual sonic screwdrivers[[edit] | [edit source]]

The Doctor's screwdriver[[edit] | [edit source]]

Main article: The Doctor's sonic screwdriver

The Doctor, throughout many of their lives, possessed a sonic screwdriver. They originally used a basic model in their first (PROSE: Venusian Lullaby [+]Loading...["Venusian Lullaby (novel)"]) and second incarnations, (TV: Fury from the Deep [+]Loading...["Fury from the Deep (TV story)"]) before upgrading in their third. (TV: The Sea Devils [+]Loading...["The Sea Devils (TV story)"]) However, according to one account, the First Doctor was unfamiliar with the sonic screwdriver when he met the Twelfth Doctor. (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"]) Similarly, the accounts depicting the Doctor's life as the Timeless Child prior to their first incarnation showed at least one of them as being unfamiliar with the sonic screwdriver and dismissive of it. (TV: Fugitive of the Judoon [+]Loading...["Fugitive of the Judoon (TV story)"]) The Doctor continued to use the model introduced during his third incarnation until it was destroyed in their fifth by a Terileptil leader. (TV: The Visitation [+]Loading...["The Visitation (TV story)"]) It wasn't until they were in their seventh incarnation before they began to use a screwdriver again, taking on various different models throughout the years. (TV: Doctor Who [+]Loading...["Doctor Who (TV story)"], Rose [+]Loading...["Rose (TV story)"], The Eleventh Hour [+]Loading...["The Eleventh Hour (TV story)"], Hell Bent [+]Loading...["Hell Bent (TV story)"], The Woman Who Fell to Earth [+]Loading...["The Woman Who Fell to Earth (TV story)"], WC: The Fourteenth Doctor's Sonic Screwdriver [+]Loading...["The Fourteenth Doctor's Sonic Screwdriver (webcast)"], AUDIO: The World Tree [+]Loading...["The World Tree (audio story)"])

The Third Doctor wields an early model of the Doctor's sonic screwdriver. (GRAPHIC: Doctor Who Evergreen [+]Loading...["Doctor Who Evergreen (illustration)"])

Early versions of their sonic screwdriver were used mainly for the picking of locks and for projecting sound so as to, for example, detonate objects and fry circuitry. (TV: The Sea Devils [+]Loading...["The Sea Devils (TV story)"]) By the time of the Ninth Doctor, the sonic was able to also be used as a sophisticated scanning device, with medical applications. (TV: The Empty Child [+]Loading...["The Empty Child (TV story)"]) Subsequent incarnations gave it even wider functionality, such as the ability to hack into computers, (TV: Smith and Jones [+]Loading...["Smith and Jones (TV story)"]) provide geolocation (TV: Evolution of the Daleks [+]Loading...["Evolution of the Daleks (TV story)"]) and actively defend against some types of assault weapons by frying their internal mechanics and causing the weapons to burst into flames and spark from the inside. (TV: Cold Blood [+]Loading...["Cold Blood (TV story)"]) The tool could create powerful frequencies and signals, (TV: Partners in Crime [+]Loading...["Partners in Crime (TV story)"], Thin Ice [+]Loading...["Thin Ice (TV story)"]) as well as use sound to carry out its functions, even to the point where three of its latest incarnations where able to create a sonic force blast powerful enough to repel and destroy a Dalek while working together, (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) as well as shoot green sonic energy waves to briefly incapacitate or stun a target. (TV: The Doctor Falls [+]Loading...["The Doctor Falls (TV story)"])

All of these incarnations utilised the same core software, though they used different hardware. While it was different individual model, for all intents and purposes the War Doctor's sonic was the same as the Eleventh Doctor's some 400 years later. (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) However, the Thirteenth Doctor, having lost the Twelfth Doctor's sonic screwdriver, created her own version. As such, hers used unique software, and was made from 21st century Earth components, as well as part of a Recall Circuit from the Stenza Homeworld. (TV: The Woman Who Fell to Earth [+]Loading...["The Woman Who Fell to Earth (TV story)"]) Although, by the time of the Fifteenth Doctor, his screwdriver featured the same software as previous models. (AUDIO: The World Tree [+]Loading...["The World Tree (audio story)"])

Romana's screwdriver[[edit] | [edit source]]

Romana II constructed her own sonic screwdriver, which was so impressive that the Doctor attempted to substitute his own with hers, but she noticed the switch. (TV: The Horns of Nimon [+]Loading...["The Horns of Nimon (TV story)"]) Her version also included a silencer. (AUDIO: Luna Romana [+]Loading...["Luna Romana (audio story)"]) She later gave it to the Doctor. (PROSE: Lungbarrow [+]Loading...["Lungbarrow (novel)"]) Nonetheless, during the final term of her presidency, her third incarnation used a sonic screwdriver. (AUDIO: Intervention Earth [+]Loading...["Intervention Earth (audio story)"])

River's screwdriver[[edit] | [edit source]]

The Twelfth Doctor gave River Song another screwdriver before River's final date with him at the Singing Towers of Darillium. (TV: The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"], Silence in the Library [+]Loading...["Silence in the Library (TV story)"]) This version of the sonic screwdriver somewhat resembled the Ninth and Tenth Doctor's model, which was notable when she met the latter in the Library, though it looked elaborately decorated and modified, featuring increased and enhanced functionality, including "dampers" and a "red setting" that allowed it to work without interference from the Doctor Moon. The Doctor gave it to River so she would be ready when she met his tenth incarnation in the Library.

Other screwdrivers[[edit] | [edit source]]

Vastra had a sonic screwdriver that was a gift from the Doctor. She used it to shatter the glass of the Crystal Palace. It had a red tip, and was similar in design to that used by the Doctor's eleventh incarnation. (COMIC: The Crystal Throne [+]Loading...["The Crystal Throne (comic story)"])

Behind the scenes[[edit] | [edit source]]

According to the fiction source REF: Doctor Who: The Visual Dictionary, a sonic screwdriver was a common and basic Time Lord device. If needed, a Time Lord could make one from scratch in very little time.
