"Chipped stone tools are a truly dynamic medium of material culture. From initial reduction to contemporary excavation, lithic artifacts undergo continuous change. The role of the properties of raw materials in determining rates of use-wear accrual is poorly understood and has rarely been assessed quantitatively. This study offers such quantification regarding four materials exploited for the production of short-term use implements at the Late Archaic FA2-13 site located just outside the city of Farmington, New Mexico. Both experimental and archaeological use-wear evidence was assessed in separate but related ways. Digital image analysis of use-wear invasiveness using ClemexVision PE and GIS analysis of use-wear homogeneity using Idrisi Kilimanjaro yielded distinct but highly complementary results. Direct testing of material properties of non-archaeological samples using a Hysitron Triboindenter served to further clarify these findings in terms of the complex relationship
