Hand Axe

A hand axe is a prehistoric stone tool worked on two faces, and is considered the longest used tool in human history. Most were made from flint or chert by knapping, and the type is characteristic of the lower Acheulean and middle Palaeolithic, roughly one point six million years ago to about one hundred thousand years ago, made and used by early human species including Homo erectus. The typical hand axe is bifacial and almond shaped, with a pointed end and a rounded base. Researchers believe hand axes were used mainly as cutting tools, particularly for butchering animals, while the wide base gave an ergonomic grip, and secondary use as a thrown weapon or a ritual object has also been proposed.
