What is there to even say? Joerg Sprave dreamed up a slingshot that shoots glass ashtrays and has a broken beer bottle attached as a bayonet. It's all pretty legit.

The slingshot is pump-powered and holds four ashtrays at a time (three in the clip plus one in the chamber). It's accurate at close range and boy can it destroy a watermelon. The grapefruit was pretty tough, but as Joerg points out while checking the damage, "That would have been a pretty painful hit, I guess." Maybe this thing is too effective? It's certainly sinister.
