softham
The following are indications of the use of a soft hammer or percussor:

-vague cones of percussion and diffuse bulbs of percussion.

-narrow butts which are often punctiform or with a lip. Lipped butts have a small overhang on the ventral surface at the edge of the butt (Owen 1988, 218). see Ohnuma & Bergman 1983
