 Other scrapers include the so-called "side scrapers" or racloirs, which are made on the longest side of a flake, and notched scrapers, which have a cleft on either side that may have been used to attach them to something else.Scrapers are typically formed by chipping the end of a flake of stone in order to create one sharp side and to keep the rest of the sides dull to facilitate grasping it.Most scrapers are either circle or blade-like in shape.
