If your normal crossbows just aren’t crazy and dangerous enough anymore, why not kick things up a notch with a laser-guided model that blasts spinning saw blades?

Meet the Blade Driver. Built by Patrick Priebe, this is probably the slickest iteration of the buzzsaw crossbow ever, propelling tiny discs of spinning death at speeds high enough to penetrate the rind of a watermelon without even slowing down. We wouldn’t recommend bringing one of these home unless you have a zombie apocalypse to survive, and the zombies are very small.

Unfortunately, Priebe isn’t offering schematics to build your own, or even a tutorial on how he did it, so if you want one you’re going to have to pry it from his cold, dead hands. We hope you have a better weapon than a crossbow that shoots laser-guided saw blades.
