Transcription: Flint is a hard stone and breaks into smooth fragments with sharp edges. By striking it with another stone or hammering on a wood or antler point, thin cutting fragments can be obtained called flakes. These blanks make ideal knives and when the edges are modified by blow or pressure chipping they can be used as scrapers, borers or engravers. Between 100 and 500 thousand years ago, man began to mount stone flakes and wooden supports.
