BACKED BLADE
Unique ID: NLM-2D52A8
Object type certainty: Certain
Workflow
status: Awaiting validation 
Grey flint with cortex backed blade. A thick oval-ended flake with part of the cortex trimmed by hard hammer strike, and with a prominent bulb on its ventral surface. Creamy dense and lighter misty patinas formed over the resultant surfaces. This was removed along one straight edge by short abrupt retouch executed from the dorsal aspect, and by battering at one end on the ventral surface. The cortex along the opposite edge was retained, perhaps as a butt for a new cutting edge. The formation and disruption of patina may indicate a flake damaged, worked and discarded, weathered in a calcareous environment, and then, finally, reused. The Neolithic period could accommodate most or all of these episodes. Suggested date: Neolithic, 4000-2350 BC.
