During the middle paleolithic, Mousterian tools were used. The Mousterian industry consisted of Levallois tools, projectile points. Such tools comprised of points and cores. "Block or cobbles of flint and other brittle fracturing rock were percussion flaked on one side until a convex "tortoise shell" shape was formed. Then, a heavy percussion blow at one end of the core removed a large flake that was convex on one side and relatively flat on the other" (http://anthro.palomar.edu/).

This YouTube video give us a an idea of how these flake tools were made.
