Blunt

blunt: A point that abruptly terminates part way up the blade with no true distal point for piercing. Typically the point is chipped in a mild excurvate or straight edge. Some feel that the point may have been used in hunting as a "stunning" weapon. However, most blunts show signs as being a conserved, former projectile, reworked into a hand held or hafted scraper.
