Abstract

Issues relating to the maintenance and renewal of stone tools have become increasingly important in studies of prehistoric technologies. This paper presents an index of reduction for unifacial side-scrapers, a common tool form in many assemblages. The index is based on a simple geometric model of flake cross-sections. It is unprejudiced by varying paths of reduction and the original sizes of tools. However, the index is potentially subject to bias resulting from variation in the form of tool blanks: In spite of these constraints, experimental data suggest that the index constitutes' a reliable measure of the extent of tool reduction.
