Here's some tech that's seriously killer. "Master bladesman" Bob Kramer lent his latest creation to PopSci, giving them the opportunity to show just how easily one of his knives can carve through everyday objects. Answer? Extremely easily.

PopSci filmed the demo in super slow-mo to highlight the blade's buttery smooth journey through the midsections of three lined-up bottles and one unfortunate Coke can. Find more videos of Kramer himself taking a few whacks at PopSci.
