At last, a knife that's so fast and furious it can slice through seemingly impenetrable Coke cans with the greatest of ease! It comes from master knife-maker Bob Kramer, whose blades sell to the tune of a pretty $10,000 (a sharp knife is indispensable in the kitchen, but just, wow). Kramer stopped by the Popular Science offices to show off his latest creation, slicing and dicing his way through paper, soda cans, and delicate male arm hair.

The video, right this way. And should you feel inspired to sharpen your own dinky blade into a lean, mean, can-slicing machine, we recommend you do so here or here.
