Shaving with an Obsidian Razor

(Video Link)

Some of you sissies are still shaving with sharpened shovels. But Mike Cook does it old school--as in using Stone Age technology. Watch him knap a slice of obsidian off a block and then shave his face with it.

Cook refers to obsidian as "the sharpest substance known to science." I don't know if that's true, but at the link, you can see electron micrographs of a surgical scalpel and an obsidian blade. The obsidian appears to have a sharper edge.

Yeah, it is true - the sharpest thing we have discovered is actually ancient tech - until we discover how to make a nanotube blade, I think we have the best we can use in obsidian. Sort of cool. Copper is also making a comeback in the operation theater as it has natural antimicrobial properties...
