User:MrThermomanPreacher/Sandbox/The Seventh and Eighth 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) 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, First Frontier) The Doctor himself claimed that he had only recently built one shortly before re-encountering, (PROSE: No Future) and that he received it as compensation after suing the Terileptils for criminal damage. (PROSE: GodEngine) 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)

This model, identified as the "Mark 5" by the Eighth Doctor, (PROSE: Alien Bodies) looked similar to the screwdriver used up until his fifth incarnation: 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. 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 red bullet-shaped crystal at its centre. (TV: Doctor Who) The Seventh Doctor claimed he patented the sonic screwdriver. (AUDIO: The Unknown) Once, while suffering from amnesia, the Eighth Doctor was able to operate this sonic screwdriver on instinct. (PROSE: EarthWorld) 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)

The Eighth Doctor had resumed using this 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) The Eighth Doctor's other choice of a diode-tipped model would become the standard for his later incarnations. (TV: The Day of the Doctor, Rose, The Christmas Invasion, The Eleventh Hour, Deep Breath)

The Eighth Doctor once commented that he felt undressed without his sonic screwdriver. (AUDIO: The Sontaran Ordeal)

A version of this screwdriver was kept in the Twelfth Doctor's office at St Luke's University. (TV: The Pilot)
