Photomicrograph (@500x) of an edge section of the unifacial tool (above) showing well-developed soft animal tissue polish on the high and low microtopography of the chert surface. According to analyst Marilyn Shoberg, the multidirectional single striations (denoted by arrows) are from grit particles dragged across the surface during use and reflect multiple cutting motions that originate at the edge of the tool.
