Jörg Sprave's arsenal of homemade slingshots is impressive, to say the least, and each time he ups the ante, escalating the size and danger of his wooden contraptions. His machete-shooting crossbow wasn't enough, and neither was his Gatling-style slingshot gun or his "slingshot of mass destruction" that fired steel balls. But this time, Sprave might have gone too far. His new slingshot shoots circular saw blades!
Saw blades are about as dangerous as you can get when it comes to razor-edged projectiles. They're heavy, sharp and totally unpredictable. But if you just fling one from a large rubber band, it's going to go berserk and loose speed, so Sprave designed his saw blade shooter with stabilization and rotational velocity in mind.
For deadly ammunition, the only step up now for Sprave and his slingshots would be tasers or frag grenades. Let's hope it doesn't come to that.
