The Doctor's sonic screwdrivers
Widely accepted
Others

The Sixth Doctor once carried an unspecified replacement model for their sonic screwdriver, but had to leave it tied to the side of a video camera in a dungeon cell in order for it to keep the visual feed disabled. (PROSE: The Nightmare Fair) He later carried another sonic model during his adventures with Crystal, Jason and Zog. (AUDIO: The Ultimate Adventure)

Uses

The Sixth Doctor's screwdriver could be used to disable a video camera indefinitely, (PROSE: The Nightmare Fair) close and seal Dalek doors and repair the TARDIS control console. He once attempted to use it to free the American Envoy from the Dalek laser wall, but this failed. (AUDIO: The Ultimate Adventure)

Behind the scenes

Given that both The Nightmare Fair and The Ultimate Adventure were written by authors who had not worked on Doctor Who for some time, Graham Williams and Terrance Dicks respectively, they may not have known the screwdriver had been phased out of the TV show at this point.
