Doctor Who 4th Doctor's Electronic Sonic Screwdriver
This awesome replica is an electronic version of the Fourth Doctor's 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 Tom Baker's reign as the Fourth Doctor, he remade yet another similar style of Sonic Screwdriver but with many more features and functions, including micro-soldering of circuitry, cutting wires and bulkheads, and even detonating DALEK explosives.
