Thirteenth Doctor's sonic screwdriver

Due to losing everything in her pockets following her regeneration and fall, the Thirteenth Doctor lost her previous incarnation's sonic screwdriver (and sonic sunglasses). As a result, the Doctor chose to build one of her own in a workshop in Sheffield. This one was far simpler in appearance than the last screwdriver with a simple steel body, and a crystal on the tip that glowed amber while in use, taken from a Stenza transport chamber. (TV: The Woman Who Fell to Earth)

It was unique from previous sonic screwdrivers in the fact that design-wise the handle was now the unique part of the sonic, as opposed to the emitter, (TV: The Woman Who Fell to Earth) which had previously either had interchangeable heads, (TV: The Sea Devils - The Visitation) an extendable emitter, (TV: Smith and Jones - The Eleventh Hour) "claws" deployed when the sonic was activated, (TV: The Eleventh Hour - Last Christmas) or a large emitter glowing in a rotating fashion. (TV: Hell Bent - Twice Upon a Time) It was also the first of the Doctor's sonic devices to have a curved handle, allowing for a more natural grip.

Comparing it to a Swiss Army knife, but without the knife, the Doctor explained that it functioned not only as a screwdriver, but as a scanner and a tin opener, and it could be used for diagnostics. (TV: The Woman Who Fell to Earth)

It had a self-rebooting feature, allowing it to restore power if drained. (TV: The Tsuranga Conundrum) It could not work on machinery if the power cells were fluctuating. (TV: Kerblam!)

When a Thijarian remnant sample overloaded the sonic, for having too many inputs, the Doctor noted that this had never happened before. This was because of the immeasurably high density of this substance, containing the remains of Thijar and all their ancestors. (TV: Demons of the Punjab) On another occasion, the sonic could calculate such an impossible density, but that "density [blew its] mind". (TV: The Battle of Ranskoor Av Kolos)

To the Doctor's extreme surprise, her sonic could be rendered inoperative by recon scout Daleks. (TV: Resolution)

History
Following the Thirteenth Doctor's regeneration, (TV: ) the screwdriver was briefly used by the Fourteenth Doctor only to be destroyed by a psychoplasmic Supreme Dalek at the Dalek Dome. This came to the dismay of the Doctor, who reflected on the screwdriver's construction in Sheffield. Soon after, as part of a deal to retrieve the TARDIS from the Golden Emperor during the 2323 Dalek invasion of Earth, the Doctor had the Old Skaro Emperor craft an identical, replacement sonic which included an integral teleporter.

The Doctor used the screwdriver to override the controls of an escape rocket to collide with the Mathematicians' Moon which sustained the psychoplasmic Daleks in the real universe. The Golden Emperor then wrested the screwdriver from the Doctor's grasp before destroying it, with the Doctor lamenting "not again!" (COMIC: ) Following the ordeal, the Doctor replaced the screwdriver with a new model. (WC:, PROSE: )
