A Doctor Who style Sonic Screwdriver I made for myself, out of copper and steel plumbing bits and etc. The grip is of thread which I wrapped. The whole thing is held together mainly with assorted adhesives and bonding agents. I've yet to add the wiring for the tip to light up, and I still need to calibrate the gyroscopic sonic flux capacitors... but other than that it's done. I tried to make it in the spirit with other Screwdrivers seen, but overall I think this is a little more Steampunkesque than any ones featured on the show. Overall, I'm pretty satisfied with it. It's about 6.75 inches long, or 17 cm. Fits comfortably in the hand and pocket, can pick a lock in less than 5 seconds.
