Pale grey flint, polished knife fragment. A chip from the cutting edge of a polished flint knife, though even in its fragmentary form this may have continued in use. A broad flake has been struck from the dorsal side, while the ventral surface is nearly flat. A curving cutting edge was produced and maintained by grinding of a narrow [c.4mm wide] zone around the edge. The object is truncated by two curved breaks, of which one at least may be recent. Suggested date: Late Neolithic, 2700-2350 BC.
