Functional Analysis of Prehistoric Flint Tools by High-Power Microscopy: A Review of West European Research

The present paper is a review of the functional analysis of prehistoric flint tool edges by means of high-power microscopy. The article, which focuses exclusively on West European research, discusses a series of methodological issues and problems related to the development and distinctiveness of the so-called "wear polishes," produced by the various materials with which prehistoric stone tools came in contact. A selection of functional observations on tool use from the Upper Paleolithic, the Mesolithic, and the Neolithic periods is presented. The archaeological part of the review is concerned with two trends in functional analysis, namely, (1) controlled site-specific studies with different levels of foci and (2) thematic studies of particular tool types, e.g., endscrapers, burins, and unmodified débitage. Finally, problems concerning the interpretation of hafting and of multiple tool use are discussed.
