A jawbone war club is an edged weapon that was in the past used by Native American tribes. [1] [2] The weapon is made out of the mandible of an elk, bison, horse or bear. It was common practice to add leather to make a weapon's handle. Such war club were sometimes painted with symbols of tribal significance. [3] Despite being a relatively primitive weapon, it was considered highly effective, and saw widespread use in prehistoric North America. The weapon was used primarily for close combat and was able to penetrate a human's chest. Occasionally the jawbone war club's teeth were polished. [4]
