 At the site of Nausharo, the use-wear analysis conducted on the flint artifacts showed a match to the experimental use-wear of a potter using the flint blades as trimming tools for pottery placed on a potter's wheel.This is significant because it gives direct evidence for the use of the blades and for the presence of a potter's wheel.Although there are debates concerning the physics of both edge polishes and edge damage which draw on the science of tribology, modern microwear analysis usually depends on the comparisons of the edge wear of modern experimentally produced samples with archaeological and/or ethnographic tools.
