          has been using stone since the period between 200000bc, and 40000bc, 
          the stone was mostly flint, this was because it flaked easily, but was 
          a very hard stone, and upon fracturing developed a very sharp edge. 
          By giving the surface a vertical blow it was possible to knock out a 
          solid cone of flint, with this solid cone they then hit near the edge 
          of the slab, this would detach a flake or chip.The cavemason would find 
          a flat surface of a rock near to where he was working, and lay the slab 
          down flat, then by more oblique downward strikes with another stone, 
          would sheer large multiple flakes, making the slab turn pear shaped, 
          now the cavemason would take a bone hammer, and proceed to chip away 
          at the cone with an outward motion, whilst holding it comfortably in 
          his hand,this was a much more delicate flaking proccess. The finished 
          result was the first tomohawk. This was ideal for slitting open animals 
          hide, and cutting up the carcass. It was also used for scraping, pounding 
          and grinding. With the result of trial and error, the cavemason used 
          the smaller pieces of flint flakes to make spear heads and even knives, 
          and with a lot of practice they soon developed their skills to make 
          other important carving tools. And so the stonemason was created.
