Switchblade tactical slingshot (vid)

http://www.youtube.com/watch?v=oNKYtyep8dM

Dude turns a switchblade into something capable of firing metal balls and arrows, and makes the switchblade more secure for stabbing.

His youtube channel's great. He's quite creative with the things he builds. He's got a machine gun slingshot run by a drill, gatling gun slingshots, pump action slings, all sorts of stuff.
