“Kunai Twister 2600“: The World’s First “Rifled“ Knife Launcher?

Last time, we announced the design and production of a new type of Kunai Launcher that gives the throwing knives a rotation. Ideally, that longitudinal rotation would stabilize the flight in the same way a rifled barrel stabilizes a bullet. We had to solve a boatload of problems on the way... but finally, the Kunai Twister 2600 was finished! The weapon actually works, but the problem is still NOT solved... see for yourself! Includes 1000 fps hispeed footage.
