on that". 2010–2015 In "The Eleventh Hour" (2010), the malfunctioning sonic screwdriver is destroyed when the Doctor tries to signal the Atraxi ships. The Doctor later receives a new one, which emerges from the newly regenerated TARDIS console. The Eleventh Doctor's sonic screwdriver is larger than its predecessor; it has a green light and metal claws that extend with a flick of the wrist. It is shown to have been created by the TARDIS as part of its automatic regeneration. In "A Christmas Carol" (2010), the Doctor advises a young Kazran Sardick to pursue romance while implying that in a similar situation in his own past he had instead gone to his room to "design a new kind of screwdriver." Also in that episode, the sonic screwdriver gets split into two pieces, one of which ends up inside a flying shark. The remaining piece is said to be signalling its other half in an effort to repair itself. The Doctor uses this to send a signal through the half inside the sky shark to open up the clouds. Afterwards, the half not in the shark is left with Kazran Sardick. The Doctor tells Kazran that he can call him for help using the Sonic; though Kazran declines to do so. The Doctor had duplicates of this screwdriver, which he continued to use throughout his travels. In "Let's Kill Hitler" (2011), it is explained that instead of having settings, this version operates through a psychic interface, basically doing whatever the user thinks of while pointing and holding down the button. This version of the screwdriver also appears, although never officially announced, to have a flashlight setting, as the Doctor is seen to have it emitting a continuous glow while not uttering the classic sonic noise. Also in the episode, the Doctor uses another modified version of his sonic, which he calls a "Sonic Cane". It is similar to a Tuxedo cane, except the top replaced with the upper portion of his screwdriver, with a metal ball cut in fourths attached to the claws. Ahead of the 50th anniversary special, a mini-episode entitled "The Night of the Doctor" (2013) was produced in which the Eighth Doctor uses the sonic screwdriver twice. The Doctor uses his telescopic screwdriver previously seen in the TV Movie, rather than his updated steampunk version which had been used in numerous Big Finish audio dramas. For the 50th
