PIERCERS/BORERS


PIERCERS/BORERS
Tools that have been retouched to a point. Piercers can be made on a flake, blade or a core:

drillbit
A drillbit is a piercer or borer that is short and whose morphology indicates that it could have been hafted and used as a drill. It is relatively easy to detect use-wear on drill bits as they have the diagnostic features of rounded points, which can sometimes be seen by the naked eye, and often striations around the point indicating a rotational motion. see Grace 1990 b. and Unger-Hamilton et al 1987
