Antlers were perhaps most important to prehistoric groups for use as flintknapping tools. Soft hammer batons for controlled percussion flaking were made from the basal portions of antlers by cutting them to length and grinding off the rough burr at the base. Antler tips, cut to lengths of 3 to 10 inches, were used as pressure flakers.
