Unique ID: NMS-D47C2E
Object type certainty: Certain
Workflow
status: Awaiting validation 
Possible plano-convex or discoidal knife of unusual form, a secondary, hard hammer struck flake with previous centripetal flake removals to the dorsal face. Of dark brown patinated flint, bulb removed by semi-invasive direct percussion struck from the dorsal face. One lateral edge is invasively retouched only on the dorsal face with seven flake scars (by pressure-flaking?), this is restricted to a natural projection of the "blank" flake.
