Twelfth Doctor's vortex manipulator
From Tardis Wiki, the free Doctor Who reference
On beginning the Twelfth Doctor's training, the Time Agency supplied him with his own vortex manipulator. On Sunstrike, it wasn't confiscated, unlike the Doctor's sonic sunglasses and sonic screwdriver, as it would not be useful to him or Keira Sanstrom.
At the end of the mission, after using the Keystone to return to the TARDIS with it, the Doctor promptly destroyed his vortex manipulator. He offered to wreck Keira Sanstrom's, but she declined. (AUDIO: Sunstrike [+]Loading...["Sunstrike (audio story)"])
