Doctor Who 3rd Doctor Sonic Screwdriver

The Sonic Screwdriver is a versatile tool and defensive device first used by The Doctor in his second incarnation for opening up hatches panels and controls. Later uses included cutting through wall sections and even as a conventional screwdriver. During the Third Doctor's exile on Earth he had a larger and more elaborately detailed version that had a decorated silver handle and black-and-yellow stripes. This version featured even more functions including detecting security traps remote detonation of mines opening doors and restraints creating ignition sparks and again removing screws and fixings
