Other sonic screwdrivers
- Liz Shaw had her own sonic screwdriver which she used to open the Doctor's TARDIS for him. (DW: Inferno)
- This appeared like the Doctor's Mark II.
- Romana constructed her own sonic screwdriver. The device impressed the Doctor, and he attempted, unsuccessfully, to swap sonic screwdrivers with her. (DW: The Horns of Nimon)
- This resembled a smaller, slimmer version of the Doctor's Mark II.
- Jack Harkness acquired a sonic blaster in his time travelling days, a more offensive multi-function device (DW: The Empty Child)
- Sarah Jane Smith had a tool she called sonic lipstick. (SJA: Invasion of the Bane)
- The Master had a similar tool called a laser screwdriver (DW: The Sound of Drums)
- Using stolen and incomplete UNIT design plans, Toshiko Sato created a sonic modulator. (TW: Fragments)
- Miss Foster had a sonic pen in Partners in Crime, with a similar design, described as sleek, to The Doctor's sonic screwdriver.
- Professor River Song has a sonic screwdriver and a sonic blaster. The screwdriver, she claims is the Doctor's own, which he gives her on one of their adventures. (DW: Silence in the Library)
Technology and Functions
The sonic screwdriver is apparently the product of Gallifreyan 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 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)
Sonic screwdrivers and similar technology also cannot unlock a deadlock seal. (DW: School Reunion)
