Description: | Chert knife, sub-oval in plan, plano-convex in profile and lozenge-shaped in section, with a snapped proximal end at the bulb of percussion and a hinge-factured distal end.The knife has been unifacially retouched along all of the left and right margins of the dorsal face.The colour of the chert is a mottled light grey and contains microcrystalline quartz that causes the surface to glisten in the light. The material has the classic look of Greensand chert that has been found in Cornwall. Greensand chert is found as pebbles and cobbles on Cornish beaches and often has a distinctive look that is different from that found associated with the Greensand ridges and the Blackdown Hills in east Devon (Rosemary Stewart pers comm).The length to breadth ratio is about 3:1, which is typical for a knife. This is a large unusual blade, possibly a Mesolithic use of local chert (Rosemary Stewart pers comm).Bond (2004) illustrates similar examples of larger retouched flakes on page 112, Fig.5.96, Nos.19-20, which is dated to the early Mesolithic, and on page 121, Fig.5.105, No.84, which is dated to the later Mesolithic.
