The '''Sonic Screwdriver''' was a versatile tool and defensive weapon used by [[the Doctor]].
==Technology and functions==
{{ImageLink}}
The sonic screwdriver was a common and basic [[Time Lord]] device. If needed, a Time Lord could made one from scratch in very little time. ([[REF]]: ''[[Doctor Who: The Visual Dictionary (2010)]]'') It is possible the [[First Doctor]] himself likely created the first sonic screwdriver during his adolescence, rather than wooing a woman. ([[DW]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'') Other alien races were known to possess similar devices, such as the [[sonic pen]] used by Miss [[Cofelia|Foster]] ([[DW]]: ''[[Partners in Crime]]'') and the [[sonic blaster]] obtained by Captain [[Jack Harkness]]. Sonic blasters were known to be made in the [[Villengard]] factory. (''[[The Empty Child]]'') The name of the device itself suggests that it functioned using sound waves, although the actual workings of the device were never fully explained.

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]].
A crystal similar to [[Metebelis Crystal]] sought after by the [[Eight Legs]] of [[Metebelis III]] was used in the Mark VI sonic screwdriver. ([[IDW]]: ''[[The Forgotten]]'') There were also electrical components. ([[DWAM]]: ''[[The Halls of Sacrifice]]'')
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]].
The screwdriver had a multitude of settings, along with different versions of settings, as the Doctor told Rose to use "setting 15B" to help him triangulate the source of the ghosts ([[DW]]: ''[[Army of Ghosts]]'') and used 34-H to sink a ship ([[DWBIT]]: ''[[Second Wave]]''). It is also said to have a setting 85. ([[DW]]: ''[[The Lazarus Experiment]]'') The Doctor told Rose to use setting 2428D to re-attach barbed wire. ([[DW]]: ''[[The Doctor Dances]]'')
== Technology and functions ==
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 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; medical diagnostics and repair of organic parts; cutting, but also re-attaching together materials such as barbed wire; operating Earth machinery such as computers and even cash machines (at regular and high eject speeds); creating a spark to light a candle; and, on the rare occasion, driving screws without touching them. Although it was primarily a tool, it could also be used as a defensive weapon, such as when the Tenth Doctor put it in a sound board to destroy the [[Robot Santa]]s. ([[DW]]: ''[[The Runaway Bride]]'') Although the [[Eighth Doctor]] once claimed that the device could destroy a Dalek's brain if held directly against the casing when activated ([[EDA]]: ''[[War of the Daleks]]''), according to the [[Tenth Doctor]], the device could not be used to wound, maim, or kill living things. ([[DW]]: ''[[Doomsday]]'') It could still be used to destroy non-living objects or mechanisms or place living creatures in circumstances where they might die, if the situation required.
[[The Doctor]] claimed to have either invented or designed the specific [[the Doctor's sonic screwdriver|sonic screwdriver which they owned]]. In fact, the [[Seventh Doctor]] claimed to have filed a [[patent]] on the technology, ([[AUDIO]]: {{cs|The Unknown (audio story)}}) and to have [[copyright]] on the design. ([[AUDIO]]: {{cs|The Quantum Possibility Engine (audio story)}})
From time to time, the sonic screwdriver needed to be recharged. ([[NSA]]: ''[[The Monsters Inside]]'', [[DWAM]]: ''[[Bizarre Zero]]'') The sonic screwdriver was self-repairing and could send out a homing signal to any parts that had been severed. ([[DW]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'')
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? You never been bored? Never had a long night? Never had a lot of [[cabinet]]s to put up?" ([[TV]]: {{cs|The Doctor Dances (TV story)}})
Sonic screwdrivers and similar technology could not unlock a [[deadlock seal]] ([[DW]]: ''[[School Reunion]]''); one of few exceptions was Miss Foster's [[sonic pen]], which was able to open the deadlock seals on and within the Adipose Industries building when the Doctor's sonic screwdriver could not. ([[DW]]: ''[[Partners in Crime]]'') Some or all versions may be ineffective against wood, or in the presence of some models of hairdryers. ([[DW]]: ''[[Silence in the Library]]''/''[[Forest of the Dead]]'', ''[[The Hungry Earth]]'', [[PDA]]: ''[[Catastrophea]]'')
Other individuals had similar devices, such as the [[sonic pen]] (which appeared to serve a near-identical function) used by [[Cofelia|Miss Foster]] ([[TV]]: {{cs|Partners in Crime (TV story)}}) and the [[sonic blaster]] used first by Captain [[Jack Harkness]] ([[TV]]: {{cs|The Empty Child (TV story)}} / {{cs|The Doctor Dances (TV story)}}) and later [[River Song]]. ([[TV]]: {{cs|Silence in the Library (TV story)}} / {{cs|Forest of the Dead (TV story)}}) [[Sarah Jane Smith]] had her [[sonic lipstick]], ([[TV]]: {{cs|Invasion of the Bane (TV story)}}, etc.) and the Doctor himself once used a [[sonic cane]]. ([[TV]]: {{cs|Let's Kill Hitler (TV story)}}) Even Missy used a [[sonic umbrella]]. ([[TV]]: {{cs|World Enough and Time (TV story)}}/{{cs|The Doctor Falls (TV story)}}) River Song also had [[River Song's sonic screwdriver|her own sonic screwdriver]] ([[TV]]: {{cs|Silence in the Library (TV story)}} / {{cs|Forest of the Dead (TV story)}}) that the Twelfth Doctor gifted her. ([[TV]]: {{cs|The Husbands of River Song (TV story)}})
==Variants of the Doctor's sonic 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)}})
[[file:Doc2Sonic.jpg|thumb|right|Earliest known sonic screwdriver in use. ([[DW]]: ''[[The War Games]]'')]]
===Mark I===
A small, simple device similar to a penlight, first used by the Doctor in his [[First Doctor|first]] ([[MA]]: ''[[Venusian Lullaby]]'') and [[Second Doctor|second incarnations]]. ([[DW]]: ''[[Fury from the Deep]]'')
====Known uses====
*Cracking the code for an aerodynamic shuttle. ([[MA]]: ''[[Venusian Lullaby]]). ''
*Opening up hatches, panels and control panels. ([[DW]]: ''[[Fury from the Deep]]'', ''[[The War Games]]'')
*For cutting through a section of a wall. ([[DW]]: ''[[The Dominators]]'')
*As a conventional screwdriver (without touching the screws). ([[DW]]: ''[[The War Games]]'')
===Mark II===
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)}})
[[file:CarnivalMonsters sonic screwdriver.jpg|right|thumb|Variation used during and following the [[Third Doctor|Third Doctor's]] [[exile on Earth]]. ([[DW]]: ''[[Carnival of Monsters]]'')]]
A larger and more elaborately detailed version, the Doctor began using this model in his [[Third Doctor|third incarnation]]. In addition to a redesign on the tip which remained the norm for the next two versions, it had a silver handle, and black and yellow stripes. It had a removable head which the Doctor would change with other heads, each doing a different function. ([[DW]]: ''[[The Sea Devils]]'')
====Known uses====
== Individual sonic screwdrivers ==
*To remotely open his workshop. ([[DW]]: ''[[Inferno]]'')
=== The Doctor's screwdriver ===
*Booby trap detector in [[the Master's TARDIS]]. ([[DW]]: ''[[Colony in Space]]'')
{{Main|The Doctor's sonic screwdriver}}
*Remote detection and detonation of land mines. ([[DW]]: ''[[The Sea Devils]]'')
[[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)}})
*To open an electronic door. ([[DW]]: ''[[The Mutants]]'')
*Creation of a spark of [[fire]] and igniting swamp gas. ([[DW]]: ''[[Carnival of Monsters]]'')
*Open electronic locks. ([[DW]]: ''[[Carnival of Monsters]]'')
*As conventional screwdriver, on large, flathead screw. ([[DW]]: ''[[The Monster of Peladon]]'')
*Overloading the brains of [[Space Greyhound]]s. ([[IDW]]: ''[[The Forgotten]]'')
*To distract giant maggots. ([[DW]]: ''[[The Green Death]]'')
===Mark III===
[[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)}})]]
The [[Fourth Doctor]] remade his sonic screwdriver into a silver version that lacked the interchangeable heads. It was capable of extending its tip.
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)}})
====Known uses====
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)}})
*Fixing a circle of [[transmat]] refractors. ([[DW]]: ''[[The Sontaran Experiment]]'')
*Breaching a [[force field]]. ([[DW]]: ''[[The Sontaran Experiment]]'')

*Disarming [[fusion bomb]]s by reversing the polarity of the neutron-flow. ([[MA]]: ''[[Cold Fusion]]'')
*Opening a door to escape confinement. ([[DW]]: ''[[Four to Doomsday]]'')
*Reversing the magnetic field on Monopticans. ([[DW]]: ''[[Four to Doomsday]]'')
*Short-circuiting androids in conjunction with a pencil, the graphite acting as a conductive material for the screwdriver's power. ([[DW]]: ''[[Four to Doomsday]]'')
*Used as a component in the [[Delta wave augmenter|delta wave augmenter]] to induce sleep. ([[DW]]: ''[[Kinda (TV story)|Kinda]]'')
===Mark IV===
=== Romana's screwdriver ===
[[file:ChangLooksThroughSonic.jpg|thumb|[[Chang Lee]] discovers the sonic screwdriver the [[Seventh Doctor]] had at [[regeneration]]. ([[DW]]: ''[[Doctor Who (1996)|Doctor Who]]'')]]
{{Main|Romana's sonic screwdriver}}
Towards the end of his [[Seventh Doctor|Seventh Incarnation]] The Doctor used a model quite similar to his Mark III except that instead of the ring around the tip being red, the tip itself was red. This was used during the [[Eighth Doctor]]'s life and had a torch built in the handle.
[[File:Romana's Screwdriver.jpg|thumb|The [[Fourth Doctor]] compares [[The Doctor's sonic screwdriver|his sonic screwdriver]] with [[Romana's sonic screwdriver|Romana's]]. ([[TV]]: {{cs|The Horns of Nimon (TV story)}})]]
[[Romana II]] constructed [[Romana's sonic screwdriver|her own sonic screwdriver]], which was so impressive that the Doctor attempted to substitute his own with hers, but she noticed the switch. ([[TV]]: {{cs|The Horns of Nimon (TV story)}}) Her version also included a silencer. ([[AUDIO]]: {{cs|Luna Romana (audio story)}}) She later gave it to the Doctor. ([[PROSE]]: {{cs|Lungbarrow (novel)}}) Nonetheless, during the final term of her presidency, her [[Romana III|third incarnation]] used a sonic screwdriver. ([[AUDIO]]: {{cs|Intervention Earth (audio story)}})
====Known Uses====
=== River's screwdriver ===
*To lock the casket containing [[the Master]]'s remains. ([[DW]]: ''[[Doctor Who (1996)|Doctor Who]]'')
{{Main|River Song's sonic screwdriver}}
*Turn Cybermen against each other. ([[DWM]]: ''[[The Flood]]'')
[[File:River Gifted her Sonic Screwdriver.jpg|thumb|River receives her sonic screwdriver. ([[TV]]: {{cs|The Husbands of River Song (TV story)}})]]
*Destroy a Dalek's brain (When placed directly against the Dalek's head) ([[EDA]]: ''[[War of the Daleks]]'')
The [[Twelfth Doctor]] gave [[River Song]] [[River Song's sonic screwdriver|another screwdriver]] before River's final date with him at the [[Singing Towers]] of [[Darillium]]. ([[TV]]: {{cs|The Husbands of River Song (TV story)}}, {{cs|Silence in the Library (TV story)}}) This version of the sonic screwdriver somewhat resembled the [[Ninth Doctor|Ninth]] and [[Tenth Doctor]]'s [[Ninth Doctor's sonic screwdriver|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 "[[damper]]s" 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]]. ([[TV]]: {{cs|Forest of the Dead (TV story)}}, [[PROSE]]: {{cs|Time Lord Technology (feature)|page=56}})
*Open a door in a force field large enough for the Doctor and his companions to travel through. ([[EDA]]: ''[[EarthWorld]]'').
===Mark V===
=== Other screwdrivers ===
In his [[Ninth Doctor|ninth incarnation]], the Doctor had a new model with a glowing blue diode at one end. The [[Tenth Doctor|tenth incarnation]] of the Doctor also carried this model, until it was burnt out after modifying an [[x-ray]] scanner to increase the radiation output. ([[DW]]: ''[[Smith and Jones]]'')
[[Quadrigger]] [[Stoyn]] possessed [[Stoyn's sonic screwdriver|a sonic screwdriver]] in his workcase aboard [[the Doctor's TARDIS]], which he had been working on shortly before the [[First Doctor]] stole the ship. ([[AUDIO]]: {{cs|The Beginning (audio story)}})

[[file:New Screwdriver.png|thumb|The Mark VII in the TARDIS console. ([[DW]]: ''[[The Eleventh Hour]]'')]]
Following the Mark VI's destruction, the Doctor received a new Sonic Screwdriver from the TARDIS. It was radically different to the previous model, having “claws” and a green diode, rather than blue. It also has copper plating in various places, both of which are similar to the new TARDIS interior. ([[DW]]: ''[[The Eleventh Hour]]'') This version of the screwdriver was destroyed when a [[sky shark]] bit it in half and swallowed the top half. ([[DW]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'')

*The sonic screwdriver was retired during the Fifth Doctor serial ''[[The Visitation]]'', as it was felt that it had become overused. It was absent for the Sixth Doctor era and all of the Seventh, except in ''[[Doctor Who (1996)|Doctor Who]]'', in which the Seventh Doctor was seen to use it to lock the Master's remains away; the Eighth Doctor recovered it at the end of the film. The tool was reintroduced with the Ninth Doctor and has become the show's most frequently used gadget besides the TARDIS itself. It has since appeared in many Seventh and Eighth Doctor audio adventures from [[Big Finish Productions]].

*During early production of 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. So, the production team secured molds from the toy replica in order to make a more reliable prop for the next season.
*Early conceptual art of the modern era Sonic Screwdriver feature a different "tube" section, with notes referring 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 feature 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. The "claws" on the Series 5 model of the sonic screwdriver may be a re-imagining of these "feet".
*There are two main versions of the Mark VI Sonic Screwdriver - one 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 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.
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)"])
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. (TV: A Christmas Carol[+]Loading...["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 crystals. (COMIC: The Forgotten[+]Loading...["The Forgotten (comic story)"])
Sonic screwdrivers and similar technology could not unlock a deadlock seal. (TV: School Reunion[+]Loading...["School Reunion (TV story)"], The Night of the Doctor[+]Loading...["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: Partners in Crime[+]Loading...["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: Utopia[+]Loading...["Utopia (TV story)"]) Some or all versions were ineffective against wood. (TV: Night Terrors[+]Loading...["Night Terrors (TV story)"], The Doctor, the Widow and the Wardrobe[+]Loading...["The Doctor, the Widow and the Wardrobe (TV story)"], The Time of the Doctor[+]Loading...["The Time of the Doctor (TV story)"], Empress of Mars[+]Loading...["Empress of Mars (TV story)"]) It didn't work in the presence of some models of hairdryers, although the Tenth Doctor stated he was working on it. (TV: Forest of the Dead[+]Loading...["Forest of the Dead (TV story)"], PROSE: Catastrophea[+]Loading...["Catastrophea (novel)"])
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)"])
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 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)"])
Narvin had a sonic screwdriver made, based on the Doctor's design, after seeing its utility when carried by the Doctor. At first he objected, preferring to call it a sonic lockpick, but then admitted the nature of his new device. (AUDIO: The Quantum Possibility Engine[+]Loading...["The Quantum Possibility Engine (audio story)"])
While trapped on Apalapucia for thirty-six years, Amy Pond cobbled together a sonic device from various pieces of technology, but insisted upon calling it a sonic probe. She later conceded that it was a "sonic screwdriver". (TV: The Girl Who Waited[+]Loading...["The Girl Who Waited (TV story)"])
