media The unlicensed fan fiction novel Time's Champion speculates that the Sixth Doctor has re-built the sonic screwdriver. He used a similar device in The Nightmare Fair, a script which was never produced for television but has been adapted twice. In the video game Daleks (published for operating systems of the early 1980s), the Doctor can use the sonic screwdriver to teleport and to defend himself against the Daleks. Public appearances Matt Smith used the Eleventh Doctor's sonic screwdriver to turn on the Christmas Lights in Cardiff in November 2010. Its appearance was cheered by the crowd. During the Doctor Who panel at San Diego Comic Con in 2018, Jodie Whittaker produced the new sonic screwdriver, prompting applause from the audience. Related devices Doctor Who The Doctor has used other sonic devices similar to the sonic screwdriver, including the "door handle" of Inferno (Liz Shaw having one of her own) and a pen-sized white noise generator in Four to Doomsday. In the 1965 episode Trap of Steel, the Doctor uses an apparently ordinary screwdriver to examine the metal of the Drahvin spaceship and other tasks. In the 1979 serial City of Death, Count Scarlioni's henchmen use a "sonic knife" to cut the glass in front of the Mona Lisa. In the 1985 serial Attack of the Cybermen, the Sixth Doctor uses a "sonic lance". In the 2005 episodes "The Empty Child" and "The Doctor Dances", Jack Harkness uses a "sonic blaster", referred to by Rose Tyler as a "squareness gun", capable of "digitising" structures by disintegrating them and then reversing the process, among other functions. The device resurfaces in "Silence in the Library" and "Forest of the Dead", now wielded by River Song. Steven Moffat confirmed in an episode of Doctor Who Confidential that the device was the same one. In "Smith and Jones", Martha Jones sarcastically asks if he's got a "laser spanner" as well as a sonic screwdriver, which he apparently did until it was stolen by Emmeline Pankhurst, described by the Doctor as a "cheeky woman". In "The Sound of Drums", the Master reveals his laser screwdriver. Unlike the sonic screwdriver, it is used as a weapon that can kill as well as artificially age its target, using technology developed by Lazarus Laboratories originally seen in "The Lazarus Experiment". It includes isomorphic controls, allowing only the Master to use the device. The design of the prop was
