 The ability of a microwear analyst has been tested in the past by presenting them with a set of experimentally produced and utilised tool in a blind experiment.The overall purpose is to provide an accurate, and precise, analytical instrument for the identification of stone tool function.It is worth noting that the precision of functional identifications may range considerably, from "scraping soft material" to "scraping fresh hide for 10 minutes" with a corresponding drop in accuracy as precision increases.
