If you have any doubt that slingshots can be dangerous weapons, Jörge Sprave, owner of the aptly-named Slingshot Channel on YouTube, will most certainly put these doubts to rest. His latest creation is a slingshot that shoots circular saw blades at unsuspecting watermelon (among other potential targets). [via Geekosystem]

    Made something similar except it was a single arm thrower with a motor to spin them up first, a simple wedge at the end of the swing arm would separate the arms enough to let the disc go flying.  Except instead of saw blades I was using laser-discs.  I could get well over 500 feet and the spinning them up really helped stability in the air.  Drawback was they were more dangerous than saw blades.   They would embed themselves at least 18 inches into the ground when they would hit.

    This project and that man are both fantastic and terrifying at the same time. I wouldn’t be surprised if we start seeing sawblade slingshots as video game weapons. Thumbs up!

    First he shoots machetes, then saw blades?  I’m moving to his neighborhood when the zombies come.

      I’m not sure why everyone thinks this sort of improvised weaponry would be useful against zombies.
      There’s no way you’d be reloading this sort of thing fast enough to take out multiple targets. You’d be better off with a simple baseball bat. And much better off with a firearm.

      If you went over to his house after the zombies took over, you’d find about four walking corpses with house-hold implements sticking out of them, and two dozen other zombies feasting on his brain.

      There was no danger. The rubber bands weren’t attached.

    Anyway, I think that using a chainsaw or a show, safety first!
