Obsidian is ridiculously sharp, because it lacks a crystal structure the edges can get to a molecular thinness. Until recently they were commonly used as surgical blades, and infact the only type of scalpel more precise is a laser. The Aztecs were even able to perform primitive brain surgery using blades fashioned out of obsidian. So I guess what my point (no pun intended) is that with a lot of sharpened obsidian rocks fastened to the side of a wooden club it would be just as sharp as any European metal sword and hypothetically a big burly Aztec might've been able to decapitate a horse with it.
