A flint crested blade, parallel-sided in plan, with a point at each end, plano-convex in profile and triangular in section, 69 mm long, 18.5 mm wide and 11 mm thick and 13 g in weight. A minute remnant of the striking platform remains at the proximal end and a faint bulb of percussion on the concave ventral face. The flint is pale grey with mottling of white and darker grey and a patch of sand-coloured patination at the distal end. No cortex remains, but the flint was likely derived from a local beach pebble. There are several flake scars from earlier removals at the distal end of the medial ridge on the dorsal side of the blade, at right angles to the length of the blade. This indicates that the flint core was later rotated through ninety degrees before removing the blade, resulting in the creation of the medial 'crest' along the blade length. This process sometimes occurs in the Early Neolithic in areas such as Cornwall, where flint is scarce.
Butler (2005) illustrates an Early Neolithic crested blade on page 120, fig.47, no.8.
