BLADE

Incomplete snapped flint blade of probable later Mesolithic date (6000BC - 3500BC). The flint tool, probably best described as a crested blade or knife, is broadly sub-rectangular in plan and has a sub-triangular in cross section. The bulb of percussion is not present, the top of the blade has been trimmed and thinned, however conchoidal fractures are present on the lower (ventral) face. The upper (dorsal) face of the blade has a number of clear facets and ridges. The long edges and ends have all been heavily retouched, especially the edges. The retouch on the left hand edge is most extensive being very neat and detailed. The right hand edge is less clear, and the retouch is slightly more haphazard. The two edges are trimmed and finished. There is no evidence of cortex (rough outer skin of the flint) on any face of the blade. The flint is a mid mottled grey colour. The source of flint is difficult to ascertain; much of the local flint is procured from glacial and riverine sources. The size of this blade is exceptional as most examples are approximately 2/3rds the size.

The blade measures 70.9mm length, 16.5mm width, is 6.5mm thick and weighs 9.21 grams
