Experimental investigations into edge performance and its implications for stone artefact reduction modelling

This paper details an experimental investigation into stone artefact performance and use, and examines the implications for maintenance and rejuvenation activities. Controlled experiments testing the performance of differently shaped working edges reveal that rates of use attrition are not constant; they are dependent upon the blank morphology's suitability to particular tasks. The evidence contributes to a broader understanding of the principles of reduction analyses by showing that morphological differences in blanks are accompanied by differences in the artefacts' functional capacity. These differences in turn affect the rate at which maintenance and rejuvenation activities will be required and therefore the extent of reduction exhibited at discard.
