hand ax in Science

A cutting or chopping tool, especially of the Lower Paleolithic Period, typically consisting of a piece of flint or other coarse stone that has been flaked on both sides to produce a sharp edge running all around the perimeter. Hand axes are core tools (produced from a found stone rather than from a processed flake) and have been found in several basic, often pointed shapes, including oval, triangular, and cordate (heart-shaped). The most common Paleolithic tool, they are especially associated with the Acheulian and some Mousterian tool cultures.
