Microscopically, the sharpest steel edge is still a saw-blade. Obsidian, and glass, are smooth-edged blades, down to close to the molecular level. Surgical scalpels, made of obsidian, leave next to no scar because they actually cut rather than tear at the microscopic level. Some knappers have custom-made the scalpels for their surgeries with excellent results.


This is correct. Obsidian surgical knives are especially good for endovascular & micro surgeries down to the micron level. They really shine for nerve damage repair. There is nothing on this planet that compares to the sharpness of a modern obsidian scalpel. As expected, they are extremely fragile and beyond expensive.
