The folks over at Neatorama have a nice reminder that sometimes technology really doesn’t have any room to improve what it tries to replace. Yes, it’s true obsidian blade can be much sharper than surgical scalps:

“A scientific study showed that obsidian blades are sharper than surgical scalpels: Obsidian is used in cardiac surgery, as well-crafted obsidian blades have a cutting edge up to five times sharper than high-quality steel surgical scalpels, with the edge of the blade reaching veritable molecular thinness. It produces a cleaner cut and less tissue trauma, which translates to faster healing and less scar tissue.”
