This is my own version of a Sonic Screwdriver from Doctor Who. It is not part of my Organization XIII OC weapons, but is in fact used by my Time Lord OC, Stashu [link]
. It is pretty long when at its full length, maybe around 22 inches. It can do just as much as the Doctor's Sonic Screwdriver, just its length is different. To extend it to this length, you simply slide that button on the handle up, and the rest pops out. The light at the top is a bit wider than the base (which is the side with the emerald jewel at the bottom), and therefore sticks out when it is deactivated. That is all I have to say.
Doctor Who, the Doctor, Time Lords, and Sonic Screwdrivers, are (C) to BBC, the British Broadcasting Coorporation.
Stashu (my OC), and custom Sonic Screwdriver design are mine!
