- As a conventional screwdriver (without touching the screws). (DW: The War Games).
- For cutting through a section of a wall. (DW: The Dominators)

Uses:
- As a means to open the shed containing garage containing the Doctor's TARDIS and Bessie.(DW: Inferno)
- Detector to discover booby traps in the Master's TARDIS. (DW: Colony in Space)

)
Mark IV
The tenth incarnation of the Doctor had a model similar to the previous one, though somewhat larger. It was burnt out after modifying an X-Ray scanner to give off more radiation to defeat a Slab, but was replaced soon after with an identical, though probably the same model.
- To transfer its powers to the viewer's remote control. (DW: Attack of the Graske)
- As a lighter. (DW: The Girl in the Fireplace)
- To partially re-constitute Ursula Blake. (DW: Love & Monsters)
- Blowing doors open. (DW: Doomsday)
- Increasing the radiation in a device such as an X-Ray scanner .(DW: Smith and Jones)
- By-Passing and turning off Security Systems. (DW: The Lazarus Experiment)
- Mark designations used purely for convenience. The Doctor and others only referred to the tool as "the sonic screwdriver".
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.
- Sarah Jane Smith had a tool she called sonic lipstick. (SJA: Invasion of the Bane)
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. The device has been mainly used as a repair tool and as a lock picker. Although it is primarily a tool, it can also be used as a defensive weapon. However, according to the Tenth Doctor, the device cannot be used to wound or kill living things. (DW: Doomsday)
Similar devices in other media
In Star Trek, Gary Seven had a sonic-screwdriver-like tool called a servo. In the CG series ReBoot, Bob used a keytool called Glitch.
