Obsidian scalpels are such a weird thing. Oh, we make scalpels out of state of the art stainless steel, but if you wanna go one step beyond go to a volcano, pick up a rock, hit it until it gets sharp and here you go.

Though they're much more expensive to make and since obsidian is reeeeaaally brittle it is potentially even more dangerous.

Obsidian scalpels: "when steel just doesn't cut it".
