"Scrapers ... are unifacially retouched tools with a steep, wide-angled edge that is suitable for a number of tasks, including scraping hides, planing wood or bone, and cutting like a knife" Whittaker 1994., 27
Scrapers are the most common type of tool found from the Middle Palaeolithic onwards. Any tool with scraper retouch on any edge, or combination of edges is a scraper.
