An axe hafted with an adhesive. Hafting is a process by which an artifact, often made of bone, stone, or metal is attached to a haft (handle [1] or strap). This makes the artifact more useful by allowing it to be launched by a bow , thrown by hand , or used with more effective leverage . When constructed properly, hafting can tremendously ...
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.
Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns. Knapped stone tools are nearly ubiquitous in pre-metal-using societies because they are easily manufactured, the tool stone raw material is usually plentiful, and they are easy to transport and sharpen.
Cleavers, found in many Acheulean assemblages such as Africa, were similar in size and manner of hand axes. The differences between a hand axe and a cleaver is that a hand axe has a more pointed tip, while a cleaver will have a more transverse "bit" that consists of an untrimmed portion of the edge oriented perpendicular to the long axis of the tool.
The distribution of stone axes is an important indication of prehistoric trade. [8] Thin sectioning is used to determine the provenance of the stone blades. In Europe, Neolithic "axe factories", where thousands of ground stone axes were roughed out, are known from many places, such as: [citation needed] Great Langdale, England
