Tokyo Metropolitan University crafted replicas of tools that might have been used in the Early Upper Paleolithic age ( about 38,00030,000 years ago ) They found that a combination of macroscopic and microscopic traces can tell us how stone edges were used.
Edges were crafted and polished using knapping and grinding techniques which would have been available at the time.
They then got to work using the tools for 15 different activities, including tree-felling, hide-processing, and butchering.
