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.
