Title |
Plano-convex knife |
|||
Description |
English: Plano-convex knife prepared on a blade like flake at least 70mm long. The dorsal face is flaked from both lateral edges, leaving a crest with traces of cortex. The outline is rather irregular. It differs from the usual Early Bronze Age plano-convex knife in having additional retouch on both lateral edges on the ventral face and removal of most of the proximal end. Possibly unfinished or an example of a late Neolithic rod. |
