Sonic screwdriver
"Harmless is just the word; that's why I like it. Doesn't kill, doesn't wound, doesn't maim. But I tell you what it does do: it is very good at opening doors."
The sonic screwdriver is a versatile tool and defensive weapon first used by the Doctor in his second incarnation.

Mark VI
"It's a screwdriver. It's sonic"
The tenth incarnation used another screwdriver after the X-ray incident. It was very similar to the Mark V, though somewhat larger and silver. It is seen blowing up in the trailer for Series 5, meaning there will be a Mark VII. It is unknown how early into the new series this change will happen and it is possible that it will be quite early on.

File:The eleventh doctors sonic screwdriver.jpg The new sonic screwdriverMark VII
The eleventh Doctor will recieve a new sonic screwdriver in series 5, that will resemble "a very shiny metal toy with a green light and, when Smith flicks his hand, metal claws that pop out at one end".
It is unknown whether The Doctor will create this version in the first episode, or at a later date.
A likely date is at the end of Episode 1
Mark ?
In the Doctor's personal future, he would upgrade the screwdriver with, in addition to the Mark V settings, red settings and damper settings. He gave it to River Song, both for her use and because it served as a way to save River's Data Ghost for uploading into the main computer of the Library. (DW: Silence in the Library / Forest of the Dead)
The nature of the red or damper settings is not yet clear; however, it is suggested that a red setting is a more powerful setting than the blue one and maybe dampers reduce outside interference with the sonic - similar to a bio damper. The 'TARDIS return switch' seen on the prop design(see right) may use similar technology to a Stattenheim remote control.
It is not yet known if this device is a modified older version of The Doctor's (current) sonic screwdriver or a newly created (albeit similar looking) device with additional modifications. The set photos indicating that Matt Smith's Doctor will have a new Sonic Screwdriver suggests that the device currently being used on the show will be modified and passed on to River.The trailer suggest however that the current Sonic Screwdriver will be destroyed in the first episode of series five, however it is unkown if the Eleventh Doctor will repair the current sonic screwdriver, modify it and then give it to River Song.
Known uses
- Activating and disabling gravity platforms. (DW: Forest of the Dead)
- Fixing light bulbs. (DW: Forest of the Dead)
- Storing the consciousness of a human being (specifically River Song's). (DW: Forest of the Dead)
Related Tools
- Liz Shaw had her own version of the Doctor's "door handle" device, which she used to open the door to the Doctor's shed. (DW: Inferno)
- Romana constructed her own sonic screwdriver. Her version so impressed the Doctor that he attempted (unsuccessfully) to swap sonic screwdrivers with her. (DW: The Horns of Nimon) She later gave it to the Doctor. (NA: Lungbarrow)
- This resembled a smaller, slimmer version of the Doctor's Mark II.
- The Master had a similar tool called a laser screwdriver (DW: The Sound of Drums)
- Captain Jack Harkness and later River Song possessed a sonic blaster. (DW: The Empty Child / The Doctor Dances, Silence in the Library / Forest of the Dead)
- Using stolen and incomplete UNIT design plans, Toshiko Sato created a sonic modulator. (TW: Fragments)
- Miss Foster had a sonic pen, with a similar design, described as sleek, to the Doctor's sonic screwdriver. (DW: Partners in Crime)
- The Doctor gave Sarah Jane Smith a sonic lipstick, a similar tool. (SJA: Invasion of the Bane) On-screen, we never see how Sarah gets either of the two sonic lipstick devices she uses. It is mentioned that The Doctor put them in K9 along with her alien detecting watch (DW: School Reunion)
- The Doctor mentions that he once had a laser spanner as well but Emmaline Pankhurst took it from him. (DW: Smith and Jones)
- Mrs Wormwood was in possession of a ring called a sonic disruptor (SJA: Enemy of the Bane).
- The Sixth Doctor defeated Cybermen using a sonic lance, similar in function but designed to work as a weapon as well.
- Jackson Lake carried what is most likely the most primitive iteration of the sonic screwdriver. His version was a regular 19th century screwdriver which he claimed to be sonic by virtue of it making a sound when it was hit against a surface. (DW: The Next Doctor)
Many of the sonic devices featured in the show are in fact incorrectly named, as their function is not always reflected accurately by their name. For example, a sonic lipstick should in fact be a device which performs the functions of a lipstick using sonic waves; similarly a sonic pen should be a device which writes using sonic energy. These devices have, however, been named to suit their appearance rather than their function.
Technology and Functions
The sonic screwdriver is apparently the product of Gallifreyan technology since other Time Lords (i.e. Romana) used the device and understood 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 explained.
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)
The screwdriver also seems to have a multitude of settings, along with different versions of settings, as he tells Rose to use "setting 15B" to help him triangulate the source of the ghosts (DW: Army of Ghosts) and it is said to have a setting 85. (DW: The Lazarus Experiment). The Doctor tells Rose to use setting 2428D to re-attach barbed wire, suggesting that the screwdriver (at least the Mark V screwdriver) has at least this many functions (DW: The Doctor Dances)
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 (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 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 Santas. (DW: The Runaway Bride) However, according to the Tenth Doctor, the device cannot be used to wound, maim or kill living things. (DW: Doomsday) It can still be used to destroy non-living objects or mechanisms or place living creatures in circumstances where they might die, if the situation requires.
Sonic screwdrivers and similar technology cannot unlock a deadlock seal (DW: School Reunion); one of few exceptions is 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. This suggests that certain sonic devices can be tailored to open certain deadlock seals, much like a key to a certain lock. (DW: Partners in Crime) However, when the Master stole The Doctor's TARDIS, he activated the TARDIS' deadlock seal and the Doctor was unable to open it using the sonic screwdriver. (DW: Utopia) However, this may be due to the fact that the Doctor stole his TARDIS and its deadlock is therefore not susceptible to the Doctor's technology in the same way as Adipose. 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, PDA: Catastrophea)
Charging
In (DW: Aliens of London) the sonic screwdriver is seen standing upright on the Tardis console. This suggests that the Tardis charges the sonic screwdriver
. This means that the sonic screwdriver must have a battery supply of some sort.
Behind the Scenes
- The tool was retired during the Fifth Doctor serial DW: The Visitation as it was felt it had become overused. It was absent for the Sixth Doctor era and all of the Seventh, except in DW: Doctor Who in which the Seventh Doctor was seen to use it to lock the Master's remains away, and 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.
- For unexplained reasons, the Tenth Doctor's Sonic Screwdriver had a green casing in DW: The Infinite Quest.
- 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 appart and 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.
- There are two main versions of the 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 January 1 trailer for Series 5 revealed that the Tenth Doctor 's sonic screwdriver will be destroyed in DW : The Eleventh Hour . In a recent interview, some details about theEleventh Doctor 's new sonic were revealed: "It’s a very shiny metal toy with a green light and, when Smith flicks his hand, metal claws that pop out at one end."
