Fifteenth Doctor's sonic screwdriver

A sonic screwdriver was owned by the Fifteenth Doctor. (AUDIO: )

Appearance and technology
As all of the Doctor's sonic screwdrivers had the same software despite their outwards appearance changing over time, (TV: ) this screwdriver was functionally the same as the Eleventh Doctor's sonic screwdriver. The Eleventh Doctor told Nora Wicker that they were the "same sonic screwdriver". (AUDIO: )

Uses

 * Operating on the same frequency as a hard-light hologram of the Eleventh Doctor's sonic screwdriver to create a crack in a Time Bubble. (AUDIO: )

History
On 16 December 2033, the Fifteenth Doctor brought his sonic screwdriver with him to help the hard-light hologram of Eleventh Doctor free Nora Wicker from a Time Bubble placed over her home, intended just to contain the World Tree that had landed on Earth on 19 August 1987. After the Eleventh Doctor told Nora the plan and exited into her garden, both Doctors readying to use their screwdrivers in sync to create a frequency to create a crack in the bubble, Nora confided that she wanted to remain in the bubble to look after the World Tree; this momentary distraction caused the Eleventh Doctor to be fractionally too slow and prevented the crack from being opened. The Fifteenth Doctor lowered his screwdriver and returned to his TARDIS. (AUDIO: )

Behind the scenes

 * Props maker Michael van Kesteren revealed to Doctor Who Magazine that the Fifteenth Doctor's sonic screwdriver was a distinct model from the model owned by the Fourteenth Doctor; Russell T Davies had certain requirements for the Fifteenth Doctor's to fulfil — unlike the Fourteenth Doctor's — with the main brief being "something every kid would want for Christmas."
