A probable Neolithic flint knife, (c.4000 - c. 2200 BC)
Description: The knife is formed from a tertiary flake sub-rectangular in shape with a roughly triangular cross section, the flat face is the ventral side of the flake. The edge is created with short invasive scaled low angle retouch it doesn't extend to each end of the edge and has been worked from both faces. The opposite edge has some crushing at the top corner around a fault in the flint, possibly to blunt a sharp section the knapper didn't deem necessary. The ventral face has a prominent bulb of percussion and clear conchoidal rippling. The flint is heavily patinated a blue white colour with iron staining across it. The retouch appears to go through this patination perhaps indicating an earlier flake reused and worked at a later date.
