Blade Driver puts a new "spin" on crossbows

German cyberpunk weapons-maker Patrick Priebe has created another dangerous toy, and this one's a doozy. Previously, he’s built things such as a laser-sighted wrist-mounted crossbow, and a hand-mounted flamethrower. His latest creation, the Blade Driver, is a full-size laser-sighted crossbow ... oh yeah, and instead of shooting arrows, it shoots spinning rotary saw blades.
The main body of the Blade Driver is aluminum, although brass is used in areas that are subjected to friction. Santos palisander, an exotic tropical wood, also makes a couple of appearances on the weapon.
The bow is made from 15 x 0.8 mm spring steel. It flings spinning Proxxon 50 x 0.8 mm circular saw blades along a Teflon slide, and subsequently through the air to an effective range of about five meters (16 feet) – depending on the target. Those blades get their spin from an adjustable electric motor that’s powered by four lithium-ion batteries, and that can get the blades spinning at speeds up to 6,000 rpm.
Aiming of the crossbow is aided by an adjustable-mount 30-milliwatt green laser.
Needless to say, this is the sort of thing that shouldn’t be used by ... well, anyone. To that end, Priebe won’t share the plans for the Blade Driver. He will, however, let you see it being put through its paces, in the video below.
