It looks like something out of a video game, but this gadget is real: a portable, mechanical, computerized, laser-guided knife gun that actually throws spinning knives end over end through the air (via Gizmodo).

Knife throwing is now a solved problem
Knife throwing is now a solved problem
This isn’t some slingshot or spiral Kunai shooter that flings those blades straight ahead, oh no — Quint Builds set out to build a gadget that can accurately throw knives just like a pro, nailing a target 10 times in a row at different distances. That meant painstakingly calculating how to spin a knife the right number of times to land tip-first, again and again and again — and employing a homemade lidar laser guidance system to measure that distance and adjust the knife’s trajectory accordingly.
Otherwise, a knife might harmlessly bounce off the target... just like mine did so many times at the last Renaissance Faire I attended.
The final contraption dispenses upwards of 10 knives from an integrated, spring-loaded magazine onto an electromagnet attached to a carriage, which zooms forward along its track at 10 meters per second thanks to a pair of motorized belts, which are in turn powered by a pair of 36V hoverboard batteries. Once the carriage reaches the midpoint of its track, the electromagnet is programmed to release the knife — letting it hit a target up to 15 feet away.
I guess you can add “knife throwing” to the list of tasks where humans are becoming obsolete!
