Abstract

Thirty-one percussion-shaped tools from the San Dieguito complex of the southern California middens have been examined. On 30 of these tools facets apparently corresponding to several regions of the thumb and the first two fingers of the right hand have been identified, as well as clearance and rake angles at the cutting edges corresponding closely to those on modern cutting tools. One of the tools seems to have been intended for left-handed usage. The evidence indicates that these tools were shaped with great precision to fit the hand and to have efficient cutting edges. Statistics on the length of the facets and the mass and height of the tools, as well as on the angles of the working edges, are given.
