Denticulate tool
In archaeology, a denticulate tool is a stone tool containing one or more edges that are worked into multiple notched shapes (or teeth), much like the toothed edge of a saw. Such tools have been used as saws, more likely for meat processing than for wood. It is possible, however, that some or all of these notches were used for smoothing wooden shafts or for similar purposes. These tools are included in the Mousterian tool industry by Neanderthal culture, proceeded by small hand axes and side scrapers. Distribution. Notable Sites. Denticulate tools have been found at a number  of notable archaeological sites around the world, include Pech de l'Aze IV in France and the El Collado site in Spain Pech de l'Azé IV. Pech de l'Azé IV is an archaeological site located in the south of France which was the home to Neanderthals during the Ice Age. Over 20,000 lithic tools were found at the site during the most recent excavations, including 43 denticulate tools, which for the purpose of this excavation were classified as "types which have two or more adjacent notches". Some of the denticulate tools found at this site were made from very thin flakes  and had complex notches resembling saws, which were most likely used for woodworking and for the processing of meat and hides.
