Fish Spine Sword

From Karate, Kungfu, Wrestling, Mixed Fighting Information Source

This is a difficult weapon to place firmly in a particular time or culture. India had a "fish spine" sword made of a metal ,comb-like blade which inflicted extremely devastating wounds to unprotected flesh. Most likely, though, the Indians developed their blade based on a weapon from New Guinea, pictured here. The New Guinea fish spine sword was made from the snout of the saw-fish, a shark common to waters throughout the Pacific. The barbs are teeth-like and very sharp. One end of the snout would be carved into a handle and then wrapped with leather or cloth. A full blow from this sturdy weapon could easily bisect or behead an opponent.
