WHAT IS THE HAND AXE?

A large bifacially worked core tool, normally oval, pointed, or pear-shaped, and one of the most typical stone tools of the Lower Paleolithic. It is the diagnostic implement of certain Lower Paleolithic industries (Abbevillian, Chellean, Acheulian), and one variety of the Mousterian. In spite of the name it was not an ax at all and probably served as an all-purpose tool. The oldest and crudest hand axes have been found in Africa; the finer, Acheulian tools are known from most of Africa, Europe, southwest Asia, and India. It was used for chopping, chipping, flaking, cutting, digging, and scraping. Hand axes first appear between 1 and 2 million years ago and they were common in assemblages for about a million years.

WHAT IS THE BIFACE ?

BIFACE: A type of prehistoric stone tool flaked on both faces or sides; the main tool of Homo erectus. The technique was typical of the handax tradition of the Lower Paleolithic period and the Acheulian cultures. Bifaces may be oval, triangular, or almond-shaped in form and characterized by axial symmetry, even if the marks made by use are more plentiful on one face or on one edge. The cutting edge could be straight or jagged and the tool used as a pick, knife, scraper, or even weapon. Only in the most primitive tools was flaking done to one side only.
