Sharpening Stone Stone tools requiring sharp edges, like knife blades, axe heads, and scrapers, would become blunt with use and wear. The edge of these stones could be sharpened by abrading each side on a hard surface, wearing down the joining edge to a sharp point. The ‘edge angle’ is the angle between a sharpening stone and a blade. If it is small, you will have a very thin, sharp edge, that will be able to make very precise cuts. If the edge angle is wider you will have a shorter blade, but it will be stronger and more resistant to breaking and chipping. Arrange the following stone tools in order of the edge angle that you would use to sharpen them: A)A tailor’s cutting blade B)An axe head C)A hide scraper D)A sewing awl
