A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history. [1] It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping , or hitting against another stone.
Flint hand axe found in Winchester. Wedges have existed for thousands of years. They were first made of simple stone. Perhaps the first example of a wedge is the hand axe (see also Olorgesailie), which is made by chipping stone, generally flint, to form a bifacial edge, or wedge. A wedge is a simple machine that transforms lateral force and ...
Wedge (hand axe): Perhaps the first example of a device designed to manage power is the hand axe, also called biface and Olorgesailie. A hand axe is made by chipping stone, generally flint, to form a bifacial edge, or wedge. A wedge is a simple machine that transforms lateral force and movement of the tool into a transverse splitting force and ...
A pointed flint hand axe was found nearby, [3] At the time, it was commonly thought that humans had been on earth for a relatively short period of time, [1] and that stone tools were used by people who simply lacked the knowledge to create metal tools. [1] Conyers was the first to argue that it was a human artefact.
There are many different types of flint axes. A specific one that appeared during the Early Stone Age was the core axe. This is an unpolished flint axe that is roughly hewn. The cutting edge is usually the widest part and has a pointed butt. Flake axes are created from the chips from the core axe. [1] Late Stone Age flint axe, about 31 cm long
Hand axes, of stone, and used without handles (hafts) were the first axes. They had knapped (chipped) cutting edges of flint or other stone. Early examples of hand axes date back to 1.6 mya in the later Oldowan, [2] in Southern Ethiopia around 1.4 mya, [3] and in 1.2 mya deposits in Olduvai Gorge. [4]

This was struck from the lateral edge of the hand-axe close to the intended cutting area, resulting in the removal of a flake running along (parallel to) the blade of the axe to create a neat and very sharp working edge. This distinctive tranchet flake can be identified amongst flint-knapping debris at Acheulean sites. [citation needed]
