Measuring retouch amounts on stone tools has been helpful for understanding human organizational strategies. Multiple retouch indices geared toward assessing retouch amounts on flake tools and unifaces have been developed, but few have been developed to evaluate retouch exclusively for bifaces. For this study, a retouch index was developed and evaluated on an experimental assemblage of bifaces. It is shown that reduction activities on bifaces may create extensive amounts of retouch that are contingent upon a number of factors from both the production and resharpening events that must be taken into consideration before understanding a biface's life history.
