The Shaving Helmet could quite possibly be the strangest gadget we’ve ever come across. Simply put, the device “uses four razors and a shaving cream irrigation system of sorts to shave a head bald in just 20 seconds.” Video after the break — thanks to reader Chris V. for the tip!

As the thoroughly bald man explains and later demonstrates on a slightly less bald man, this seemingly lethal device is actually pretty efficient.
