when did the doctor first use a sonic screwdriver
Sonic screwdriver The sonic screwdriver was first introduced in 1968 in the story Fury from the Deep, and used twice more (The Dominators and The War Games) during the Second Doctor's tenure. It became a popular tool for the Third Doctor and Fourth Doctor. It was finally written out of the series in 1982 due to the limitations it caused when writing for the show. It then featured briefly in the 1996 Doctor Who television movie, before making a full return in the 2005 continuation of the series.
The Next Doctor The Doctor lands his TARDIS in London on Christmas Eve, 1851. Overhearing cries for help, he encounters a man calling himself "The Doctor" and his companion Rosita, attempting to capture a Cybershade. The Cybershade escapes the trio. The Doctor, in talking to the man, comes to believe he may be a future incarnation of himself, who is suffering from amnesia. The man, dubbed the Next Doctor, takes the Doctor to a nearby house of a recently deceased reverend, believing him tied to a series of disappearances around London and the Cybershade. Inside, they discover a pair of Cybermen data-storage infostamps, which the Next Doctor recalls holding the night that he lost his memories. The two are attacked by Cybermen and the Doctor attempts to fight them off with a cutlass, but the Next Doctor kills them using electrical discharge from the infostamps.
