Title |
Neolithic or Bronze Age borer |
||
Description |
English: A large hand held boring tool or possible pointed "fabricator" made on a core of surface flint of unusual dark reddish colour with a large area of pale cortex remaining at the butt end. The flint exhibits natural thermal fractures which have been enhanced by first invasively flaking and then a second row of steep flaking to form a point at one end.
Most of the flakes have been removed from both lateral edges of one face and the edges themselves are heavily abraded from use although the tip is fairly fresh and unworn, suggesting its use as a rotary boring tool for enlarging holes rather than a pick. Fabricators, sometimes made on cores, were in use from the Mesolithic through to the Late Bronze Age, though it is more likely to be a borer of the Late Neolithic or Early Bronze Age. 98 x 71.5 x 10mm. |
