Well it is a tool/rock made from volcanic glass. The Aztec used it a lot to build statues and shelter.

Obsidian is well suited to 'flaking" or "napping" which is the art of creating a sharp edge.

Obsidian will flake down to a molecular edge, being a type of naturally occurring glass it is high on the hardness scale.

Even today, some surgical scalpel tips are fabricated from obsidian.
