Stone Tool Making Techniques: Soft-Hammer thinning and resharpening

Soft-hammer percussion flaking involved detaching flakes with a soft indentor, such as an antler, bone, wood, or soft stone such as limestone or sandstone.  In bifacial flaking, flakes were removed from two faces of the stone from the one platform edge, and soft hammers were ideal for thinning a biface.
