Obsidian Knives for Surgery

Obsidian is a type of volcanic glass that has an extremely sharp edge when filed down. Some of the finest examples of blades made out of obsidian were discovered in Mesoamerica over 2,500 years ago. Dr. Don Crabtree re-discovered the ancient technology about twelve years ago, and along with other surgeons, believes there might be a place for obsidian blades in current medicine. Blades produced by Dr. Crabtree have been used in experimental microsurgery with excellent results.

The prismatic glass blade is infinitely sharper than a honed steel edge, and these blades can be produced in a wide variety of shapes and sizes. When used in experimental surgeries on animals, the blades yield comparable and even better healing than cuts made with traditional scalpels.
