Title |
serrated blade |
||
Description |
English: A large and thick blade worked on a brown flint nodule with large smooth opaque light grey inclusions. The blade has reached the base of the core and so the distal end and most of the right margin carries cortex. The blade has been prepared for removal by striking off a set of converging flakes to leave a very flat and thinned proximal end before removing the blade with a soft hammer. The left margin truncates a large transverse flake scar so the blade came from a 2 platform core with platforms at right angles to each other. The straight left margin from the distal end to the mesal has a serrated retouch of small, even sized semi-abrupt scars. Some is on the ventral side but some of them may be damage. Towards the proximal end is a shallow, abruptly worked notch. A small notch is formed with similar flakework between the proximal end and the right margin and fine semi-abrupt edgework continues up to the cortex at the mesal part of the margin. It is a possibility that the thinned proximal end with attendant notches and blunting retouch was intended for hafting and the serrated part of the left margin was a saw. |
