Mayo scissors have semi-blunt ends, a feature that distinguishes them from most other surgical scissors. Metzenbaum scissors are, however, similar in that the ends are the same on both scissor halves, but its handles are longer and its middle section is slightly narrower.
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 ().
In archaeology, a hammerstone is a hard cobble [1] used to strike off lithic flakes from a lump of tool stone during the process of lithic reduction. [2] The hammerstone is a rather universal stone tool which appeared early in most regions of the world including Europe , India [ 3 ] and North America .
Using a hammerstone produces what is called a preform, which is the core of the tool in need of more detailed refinements. The next technique allows for an increased level of detail; using a soft hammer (often made of wood or bone), one can chip away flakes of material with more precision.
Lithic tools produced this way may be bifacial (exhibiting flaking on both sides) or unifacial (exhibiting flaking on one side only). Mount William stone axe quarry in Australia Cryptocrystalline or amorphous stone such as chert , flint , obsidian , and chalcedony , as well as other fine-grained stone material, such as rhyolite , felsite , and ...
Heavy-duty tools are mainly cores. A chopper has an edge on one side. It is unifacial if the edge was created by flaking on one face of the core, or bifacial if on two. Discoid tools are roughly circular with a peripheral edge. Polyhedral tools are edged in the shape of a polyhedron. In addition there are spheroidal hammer stones.
A flint flake tool from the Neolithic, found in Hertfordshire, England. In archaeology, a flake tool is a type of stone tool that was used during the Stone Age that was created by striking a flake from a prepared stone core. People during prehistoric times often preferred these flake tools as compared to other tools because these tools were ...
