Aside from the invention of the wheel and the light bulb, there is no other invention that has benefited the advancement of mankind for good (for the most part) than the knife. A simple, short cutting implement has helped us achieve agriculture, taken down prey and predators, ward off fellow human attackers, and provided a way for us to pick our teeth in the coolest, most dangerous way possible.

It can be easy to see how so many people overlook the knife. In today’s world, it’s just a fork’s tag team partner and a metal stick used to slather peanut butter on things. Or it’s an impractical  decorative tchotchke that you find at a flea market to use as wall art or something (if you’re a single, lonely man). But knives are more than what they seem.

Let’s cut the crap and trim away the nonsense with some interesting facts about knives.

Obsidian Scalpels

Obsidian scalpels give surgeons a cutting edge. In lieu of traditional steel, many top surgeons prefer scalpels made of obsidian (a type of volcanic glass), as they are able to make finer, exact cuts on even the toughest materials. CRACKED.COM
