In this image, the micrograph on the top right (D) shows bright polish and striations perpendicular to the edge. On the top right (E) shows discontinuous polish, which indicates that this location was not as heavily used as other areas of the tool’s surface. Bottom left (F) shows a high spot with well-developed polish and surrounding flake scars without polish, which suggests that this tool was re-sharpened and therefore used during multiple processing events.
