Brown chert blade with a long straight edge and rough serrated margins on a plain light background.

Blade

A long, narrow prehistoric blade of brown-yellow chert lies horizontally against a pale grey ground. Its upper edge is straight and finely retouched, while the lower edge shows small irregular chips and a broken, angled end at right. The surface shows faint longitudinal ridges left by earlier flake removals.

Look closer: Small chipped notches along the lower edge show the retouching used to shape the blade.
