This replica of the fourth doctor's electronic screwdriver features sound FX.
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 Fourth Doctor’s reign, 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.
This release from 2011 of the electronic version of the Fourth Doctor’s Sonic Screwdriver features 2 sounds and spring loaded sound activation.
Just a dozen have been unearthed, what is over a dozen years since first available.
