BACKED BLADE
Unique ID: NLM-8F8C84
Object type certainty: Possibly
Workflow
status: Awaiting validation 
Dark grey flint with cortex, possible backed blade. Small triangular-section flake with broad flakes struck from its dorsal side and with a positive hinge fracture at one end of its ventral surface. Edge-on impacts impart a probably misleading impression of serration. The lack of patina on struck surfaces may point to the subsequent incorporation of the object into a sealed deposit. Cortex has re-formed over one plane of the dorsal side. Suggested date: Neolithic, 4000-2350 BC
Length: 22.3mm, Width: 19.0mm, Thickness: 6.3mm, Weight: 3.09gms
