  Paleolithic hand axes were teardrop-shaped stone tools with two sharpened edges that met at a point. In one method, they were made by roughly chipping away flakes from the edges with a hammer and then sharpening the edges by chipping away smaller flakes. Finally, a pointed stick was used to pry off tiny flakes of stone.
