Fourteenth Doctor's sonic screwdriver

A sonic screwdriver was owned by the Fourteenth Doctor, which had similar design elements to previous models. (PROSE: )

Appearance and technology
The sonic screwdriver had similar design elements to previous sonic screwdrivers and other devices: the wide area dispersal petals and the resonator cage were similar to the Eleventh Doctor's sonic screwdriver; the handle was similar to the Ninth and Tenth Doctor's sonic screwdriver, which was made from coral like the TARDIS; the frequency and intensity dials were similar to the Master's laser screwdriver; the cage around the central sonic cluster was similar to that of the Twelfth Doctor's second model (PROSE: ) and a Dalek gunstick; (TV:, AUDIO: , etc.) and the primary sonic emitter was similar to the bullet-shaped emitter on the sonic screwdriver belonging to the Third, Fourth, and Fifth Doctors and the sonic screwdriver belonging to (PROSE: ) the Seventh (TV: ) and Eighth Doctors. (PROSE: ) When used, the screwdriver had a "bright blue buzz". (PROSE: )

The activation button also had circular Gallifreyan embossed into it and the function access controls were located at the pommel, with a hexagonal cutout at the very base. (WC:, PROSE: )

Uses

 * Scanning the walls of a cave to identify the technology within. (PROSE: )
 * Operating on a precise resonance to dislodge a chunk of rock from a cave ceiling, a pitch so high it was inaudible to even the Doctor with his Time Lord ears. (PROSE: )
 * Adjusting a pulley to increase and decrease the height of a seemingly dangerous stalactites-spiked platform. (PROSE: )
 * Resonating with mortar in a brick wall to break it apart. (TV: )
 * Generating shields to stop bullets and neural anesthetic shots. (TV: )
 * Projecting a display screen to analyze various bits of information. (TV: )
 * Intercepting Wrarth Warriors' teleportation beam. (
 * Removing a fence panel. (TV: )

History
After the Thirteenth Doctor's sonic screwdriver fell into the Fourteenth Doctor's possession following his regeneration, he used it for a short while to scan inside the Dalek Dome until it was destroyed by a fake Supreme Dalek. He later got an identical one made for him that he used to change the direction of the Daleks' escape rocket to hit the Mathematicians' Moon. It was then destroyed by the fake Golden Emperor. (COMIC: ) He later replaced it. (WC:, PROSE: , )

During his travels, the TARDIS brought the Doctor to a Sycorax spaceship piloted by the Queen of the Sycorax during Christmas, (COMIC: ) however he was unaware that he was in anything other than a cave. While exploring, the Doctor came across a Strombok lodged in a fissure, whereupon the Doctor pulled the screwdriver out from his coat to dislodge a slab of rock to prevent the fissure from closing. On several occasions, he used the screwdriver to scan the veins of silver embedded in the walls of the craft, but only got unclear readings each time. He also used the screwdriver to adjust a pulley to raise and lower a platform with stalactites facing down towards a group of humans, to demonstrate that the trap physically couldn't actually harm them as it was designed merely to provoke fear, as the craft was powered by psychic turbines that fed off pain.

Behind the scenes

 * Some of the design choices of the sonic screwdriver were Easter Eggs; as revealed by props makers Michael van Kesteren and Barry Jones, some of the out-of-universe details included:
 * The "frequency and intensity dials" portion of the sonic contained a ball detent ratchet — as Phil Sims wanted "knurled" detail on the sonic — so the dials, when turned, made a clicking noise.
 * The hexagonal indentation in the pommel was designed to fit an ordinary screwdriver head.
 * The wide area dispersal petals resembled the officially-named "Eleventh Doctor's flippy-out petals"
 * The cage around the central sonic cluster was meant to reference Rusty's line to the Twelfth Doctor in Into the Dalek: "You would make a good Dalek."
 * That the crackled coral effect on the screwdriver — like Nine and Ten's — was.
 * Furthermore, Van Kesteren revealed that the Fifteenth Doctor's screwdriver was a distinct model from the Fourteenth's.
