In archaeology, a uniface is a specific type of stone tool that has been flaked on one surface only. [ 1 ] [ 2 ] There are two general classes of uniface tools: modified flakes and formalized tools, which display deliberate, systematic modification of the marginal edges, evidently formed for a specific purpose.
Adzes have been used since the Stone Age. They are used for smoothing or carving wood in hand woodworking , and as a hoe for agriculture and horticulture . Two basic forms of an adze are the hand adze (short hoe)—a short-handled tool swung with one hand—and the foot adze (hoe)—a long-handled tool capable of powerful swings using both ...
The latter two, softer hammers can produce more delicate results. However, a hand axe's technological aspect can reflect more differences. For example, uniface tools have only been worked on one side and partial bifaces retain a high proportion of the natural cortex of the tool stone, often making them easy to confuse with chopping tools.
In prehistoric archaeology, scrapers are unifacial tools thought to have been used for hideworking and woodworking. [1] Many lithic analysts maintain that the only true scrapers are defined on the base of use-wear, and usually are those that were worked on the distal ends of blades—i.e., "end scrapers" (French: grattoir).
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.
Percussion tools for hitting - such as mallets, axes, adzes, bouchards and toothed hammers. Tools for rough shaping of stone, to form a block the size needed for the carving. These include feathers and wedges and pitching tools. Chisels for cutting - such as lettering chisels, points, pitching tools, and claw chisels. Chisels, in turn, may be ...
Other ground stone tools include adzes, celts, and axes, which are manufactured using a labor-intensive, time-consuming method of repeated grinding against a harder stone or with sand, often using water as a lubricant. These tools are often made using durable finer-grained materials rather than coarse materials.
Also five adzes, a corner chisel, two froes, and a twybil. [citation needed] In Minoan Crete, the double axe had a special significance, used by priestesses in religious ceremonies. [citation needed] In 1998, a labrys, complete with an elaborately embellished haft, was found at Cham-Eslen, Canton of Zug, Switzerland.
