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 (TV story)|Doomsday]]'') and a version of [[Amy Pond]] who had been stuck on [[Apalapucia]] for 36 years. ([[TV]]: ''[[The Girl Who Waited (TV story)|The Girl Who Waited]]'') The [[Tenth Doctor|Tenth]] ([[TV]]: ''[[Doomsday (TV story)|Doomsday]]'') and [[Eleventh Doctor|Eleventh]] ([[TV]]: ''[[The Girl Who Waited (TV story)|The Girl Who Waited]]'') Doctors openly disliked this and corrected those who did so. The [[Ninth Doctor|Ninth]] ([[TV]]: ''[[The Doctor Dances (TV story)|The Doctor Dances]]'') and [[Twelfth Doctor]]s ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'') also defended when others claimed it was inferior to other sonic devices like a [[sonic blaster]] or [[sonic trowel]].
== Technology and functions ==
Identified by the [[Dalek]]s as a "[[sonic probe]]", ([[TV]]: ''[[Doomsday (TV story)|Doomsday]]'') the sonic screwdriver was considered to be very advanced [[Gallifrey]]an technology, ([[PROSE]]: ''[[Heart of TARDIS (novel)|Heart of TARDIS]]'') 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 (TV story)|The Woman Who Fell to Earth]]'') During the [[Dalek-Movellan War]], [[Davros]] dismissed the sonic screwdriver as a "simple" tool. ([[AUDIO]]: ''[[The Triumph of Davros (audio story)|The Triumph of Davros]]'')
[[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]]: ''[[The Unknown (audio story)|The Unknown]]'') and to have [[copyright]] on the design. ([[AUDIO]]: ''[[The Quantum Possibility Engine (audio story)|The Quantum Possibility Engine]]'')


The '''sonic screwdriver''' is a tool and defensive weapon used by [[the Doctor]] from his [[Second Doctor|second incarnation]] onward. It is also part of toolbox for [[the Doctor's TARDIS]]. The Doctor's [[Tenth Doctor|tenth incarnation]] sometimes referred to it as "'''the sonic'''".
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]]: ''[[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 Doctor defensively 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]]'')


==Variants==
Other individuals had similar devices, such as the [[sonic pen]] (which appeared to serve a near-identical function) 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 (TV story)|Invasion of the Bane]]'', etc.) and the Doctor himself once used a [[sonic cane]]. ([[TV]]: ''[[Let's Kill Hitler (TV story)|Let's Kill Hitler]]'') Even Missy used a [[sonic umbrella]]. ([[TV]]: ''[[World Enough and Time (TV story)|World Enough and Time]]''/''[[The Doctor Falls (TV story)|The Doctor Falls]]'') River Song also had [[River Song's sonic screwdriver|her own sonic screwdriver]] ([[TV]]: ''[[Silence in the Library (TV story)|Silence in the Library]]'' / ''[[Forest of the Dead (TV story)|Forest of the Dead]]'') that the Twelfth Doctor gifted her. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'')
===The Doctor's sonic screwdriver===
====Mark I====
A small, simple device very like a penlight. It was first introduced by the Doctor in his [[Second Doctor|second incarnation]]. ([[DW]]: ''[[Fury from the Deep]]'')  


'''Uses''':
From time to time, the sonic screwdriver needed to be recharged. ([[PROSE]]: ''[[The Monsters Inside (novel)|The Monsters Inside]]'', [[COMIC]]: ''[[Bizarre Zero (comic story)|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]]'') One account held that a sonic screwdriver was powered by a type of [[crystal]] that was similar to the [[Metebelis crystal]]s. ([[COMIC]]: ''[[The Forgotten (comic story)|The Forgotten]]'')
*Opening up hatches and panels ([[DW]]: ''[[Fury from the Deep]]'', ''[[The War Games]]'') and control panels. ([[DW]]: ''[[The War Games]]'')  
*As a conventional screwdriver (without touching the screws). ([[DW]]: ''[[The War Games]]'').
*For cutting through a section of a wall. ([[DW]]: ''[[The Dominators]]'')


====Mark II====
Sonic screwdrivers and similar technology could not unlock a [[deadlock seal]]. ([[TV]]: ''[[School Reunion (TV story)|School Reunion]]'', ''[[The Night of the Doctor (TV story)|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 (TV story)|Partners in Crime]]'') It also couldn't unlock the doors to the TARDIS if they had been manually locked at the console. ([[TV]]: ''[[Utopia (TV story)|Utopia]]'') Some or all versions were ineffective against [[wood]]. ([[TV]]: ''[[Night Terrors (TV story)|Night Terrors]]'', ''[[The Doctor, the Widow and the Wardrobe (TV story)|The Doctor, the Widow and the Wardrobe]]'', ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'', ''[[Empress of Mars (TV story)|Empress of Mars]]'') It didn't work in the presence of some models of [[hairdryer]]s, although the Tenth Doctor stated he was working on it. ([[TV]]: ''[[Forest of the Dead (TV story)|Forest of the Dead]]'', [[PROSE]]: ''[[Catastrophea (novel)|Catastrophea]]'')
A larger and more elaborately detailed version, the Doctor introduced in his [[Third Doctor|third incarnation]]. During his [[Fifth Doctor|fifth incarnation]] it was destroyed by the [[Terileptil]] leader. ([[DW]]: ''[[The Visitation]]''). By his [[Seventh Doctor|seventh incarnation]] the Doctor had a new one. ([[DW]]: ''[[Doctor Who: The TV Movie]]'').


'''Uses''':
== Individual sonic screwdrivers ==
*As a means to open the shed containing garage containing [[the Doctor's TARDIS]] and [[Bessie]].([[DW]]: ''[[Inferno]]'')
=== The Doctor's screwdriver ===
*Detector to discover booby traps in [[the Master]]'s [[Type 40|TARDIS]]. ([[DW]]: ''[[Colony in Space]]'')
{{Main|The Doctor's sonic screwdriver}}
*Detecting and setting off land mines from a distance. ([[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]]: ''[[Venusian Lullaby (novel)|Venusian Lullaby]]'') and [[Second Doctor|second incarnations]], ([[TV]]: ''[[Fury from the Deep (TV story)|Fury from the Deep]]'') before [[Third Doctor's sonic screwdriver|upgrading]] in [[Third Doctor|their third]]. ([[TV]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'') 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 (TV story)|Twice Upon a Time]]'') 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 (TV story)|Fugitive of the Judoon]]'') 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]]: ''[[The Visitation (TV story)|The Visitation]]'') 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]]: ''[[Doctor Who (TV story)|Doctor Who]]'', ''[[Rose (TV story)|Rose]]'', ''[[The Eleventh Hour (TV story)|The Eleventh Hour]]'', ''[[Hell Bent (TV story)|Hell Bent]]'', ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'', [[WC]]: {{cs|The Fourteenth Doctor's Sonic Screwdriver (webcast)}}, [[AUDIO]]: {{cs|The World Tree (audio story)}})

====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]]: ''[[Doctor Who Evergreen (illustration)|Doctor Who Evergreen]]'')]]
In his [[Ninth Doctor|ninth incarnation]] the Doctor had a new model with a glowing blue laser-like beam at one end.
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]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'') 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]]: ''[[The Empty Child (TV story)|The Empty Child]]'') Subsequent incarnations gave it even wider functionality, such as the ability to [[hacking|hack]] into [[computer]]s, ([[TV]]: ''[[Smith and Jones (TV story)|Smith and Jones]]'') provide [[geolocation]] ([[TV]]: ''[[Evolution of the Daleks (TV story)|Evolution of the Daleks]]'') 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]]: ''[[Cold Blood (TV story)|Cold Blood]]'') The tool could create powerful frequencies and signals, ([[TV]]: ''[[Partners in Crime (TV story)|Partners in Crime]]'', ''[[Thin Ice (TV story)|Thin Ice]]'') 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]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') as well as shoot green sonic energy waves to briefly incapacitate or stun a target. ([[TV]]: ''[[The Doctor Falls (TV story)|The Doctor Falls]]'')


[[Image:sonicscrewdriver.jpg|thumb|220px|right|A sonic screwdriver used by the Doctor's [[Ninth Doctor|ninth incarnation]]]]
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]]: ''[[The Day of the Doctor (TV story)|The Day of the Doctor]]'') 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 (TV story)|The Woman Who Fell to Earth]]'') 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)}})

==Technology and Functions==
While trapped on [[Apalapucia]] for thirty-six years, [[Amy Pond]] cobbled together [[Amy Pond's sonic probe|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 (TV story)|The Girl Who Waited]]'')
The sonic screwdriver is apparently the product of [[Gallifrey]]an technology since other Time Lords (i.e. [[Romana]]) use the device and understand it enough to construct their own versions of it. The name of the device itself suggests that it functions using soundwaves, although the actual workings of the device have never been explicitly explained.  


The different versions of the Doctor's sonic screwdrivers have 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; creating a spark to light a candle. Although it is primarily a tool, it can 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]]'') However, according to the [[Tenth Doctor]], the device cannot be used to wound or kill living things. ([[DW]]: ''[[Doomsday]]'')
[[Vastra]] had [[Vastra's sonic screwdriver|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 (comic story)|The Crystal Throne]]'')


Sonic screwdrivers and similar technology also cannot unlock a [[deadlock seal]]. ([[DW]]: ''[[School Reunion]]'')
== Behind the scenes ==
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.

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) and a version of Amy Pond who had been stuck on Apalapucia for 36 years. (TV: The Girl Who Waited) The Tenth (TV: Doomsday) and Eleventh (TV: The Girl Who Waited) Doctors openly disliked this and corrected those who did so. The Ninth (TV: The Doctor Dances) and Twelfth Doctors (TV: The Husbands of River Song) 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) the sonic screwdriver was considered to be very advanced Gallifreyan technology, (PROSE: Heart of TARDIS) 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) During the Dalek-Movellan War, Davros dismissed the sonic screwdriver as a "simple" tool. (AUDIO: The Triumph of Davros)

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) and to have copyright on the design. (AUDIO: The Quantum Possibility Engine)

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) 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)

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) and the sonic blaster used first by Captain Jack Harkness (TV: The Empty Child / The Doctor Dances) and later River Song. (TV: Silence in the Library / Forest of the Dead) Sarah Jane Smith had her sonic lipstick, (TV: Invasion of the Bane, etc.) and the Doctor himself once used a sonic cane. (TV: Let's Kill Hitler) Even Missy used a sonic umbrella. (TV: World Enough and Time/The Doctor Falls) River Song also had her own sonic screwdriver (TV: Silence in the Library / Forest of the Dead) that the Twelfth Doctor gifted her. (TV: The Husbands of River Song)

From time to time, the sonic screwdriver needed to be recharged. (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) One account held that a sonic screwdriver was powered by a type of crystal that was similar to the Metebelis crystals. (COMIC: The Forgotten)

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) It also couldn't unlock the doors to the TARDIS if they had been manually locked at the console. (TV: Utopia) Some or all versions were ineffective against wood. (TV: Night Terrors, The Doctor, the Widow and the Wardrobe, The Time of the Doctor, Empress of Mars) 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, PROSE: Catastrophea)

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) and second incarnations, (TV: Fury from the Deep) before upgrading in their third. (TV: The Sea Devils) 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) 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) 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) 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, Rose, The Eleventh Hour, Hell Bent, The Woman Who Fell to Earth, 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)

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) 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) Subsequent incarnations gave it even wider functionality, such as the ability to hack into computers, (TV: Smith and Jones) provide geolocation (TV: Evolution of the Daleks) 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) The tool could create powerful frequencies and signals, (TV: Partners in Crime, Thin Ice) 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) as well as shoot green sonic energy waves to briefly incapacitate or stun a target. (TV: The Doctor Falls)

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) 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) 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) Her version also included a silencer. (AUDIO: Luna Romana) She later gave it to the Doctor. (PROSE: Lungbarrow) Nonetheless, during the final term of her presidency, her third incarnation used a sonic screwdriver. (AUDIO: Intervention Earth)

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

Main article: River Song's sonic screwdriver
River receives her sonic screwdriver. (TV: The Husbands of River Song)

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, Silence in the Library) 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.
