Seventh Doctor's sonic screwdriver
The Seventh Doctor acquired a sonic screwdriver at an unspecified point of his life. Many contradictory accounts existed, including one which claimed he had acquired it at some point before meeting Bernice Summerfield, (AUDIO: Love and War [+]Loading...["Love and War (audio story)"]) and another, which claimed he acquired it from himself on a parallel Earth where the species Homo Reptilicus had conquered the Earth and killed his third incarnation. (PROSE: Blood Heat [+]Loading...["Blood Heat (novel)"], First Frontier [+]Loading...["First Frontier (novel)"]) The Doctor himself claimed that he had only recently built one shortly before re-encountering Mortimus, (PROSE: No Future [+]Loading...["No Future (novel)"]) and that he received it as compensation after suing the Terileptils for criminal damage; (PROSE: GodEngine [+]Loading...["GodEngine (novel)"]) the Terileptils having destroyed the sonic screwdriver used by the Fifth Doctor. (TV: The Visitation [+]Loading...["The Visitation (TV story)"]) The Eighth Doctor claimed that this screwdriver was a spare model that had "rolled under the TARDIS console and remained there" until the Seventh Doctor found it. (PROSE: Frontier Worlds [+]Loading...["Frontier Worlds (novel)"])
This model, identified as the "Mark 5" by the Eighth Doctor, (PROSE: Alien Bodies [+]Loading...["Alien Bodies (novel)"]) looked similar to the screwdriver used by his third, fourth and fifth incarnations: it was silver with a brass trim ring in the lower grip and a handle that resembled that of the previous sonic screwdrivers', now with a flat base and handle. Its upper section was able to undergo telescopic collapse for ease of carrying, and, at its top, it held an emitter with a silver ring and a cherry red bullet-shaped crystal at its centre. (TV: Doctor Who [+]Loading...["Doctor Who (TV story)"]) The Seventh Doctor claimed he patented the sonic screwdriver. (AUDIO: The Unknown [+]Loading...["The Unknown (audio story)"]) Once, while suffering from amnesia, the Eighth Doctor was able to operate this sonic screwdriver on instinct. (PROSE: EarthWorld [+]Loading...["EarthWorld (novel)"]) This version remained in the Eighth Doctor's use throughout his life, up until its destruction at the hands of a Cyber-Leader on Earth. (COMIC: The Flood [+]Loading...["The Flood (comic story)"])
The Eighth Doctor would later replace it with a drastically redesigned model that featured a diode-tip (AUDIO: The Great War [+]Loading...["The Great War (audio story)"]); a feature that become the standard for his later incarnations. (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"], Rose [+]Loading...["Rose (TV story)"], The Eleventh Hour [+]Loading...["The Eleventh Hour (TV story)"], Hell Bent [+]Loading...["Hell Bent (TV story)"], The Woman Who Fell to Earth [+]Loading...["The Woman Who Fell to Earth (TV story)"]) He eventually resumed using the Seventh Doctor's model by the end of his life during the Last Great Time War. It was the second and final model the Doctor used thus far that bore an emitter-ring head. (TV: The Night of the Doctor) At one point, he commented that he felt undressed without his sonic screwdriver. (AUDIO: The Sontaran Ordeal [+]Loading...["The Sontaran Ordeal (audio story)"])
A version of this screwdriver was kept in the Twelfth Doctor's office at St Luke's University. (TV: The Pilot [+]Loading...["The Pilot (TV story)"])
The sonic was found in the Remembered TARDIS by Jo Jones. (TV: The Three Doctors [+]Loading...["The Three Doctors (TotT TV story)"])
