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).
This method provides much greater control over the size and shape of the final flake which would then be employed as a scraper or knife although the technique could also be adapted to produce projectile points known as Levallois points. Scientists consider the Levallois complex to be a Mode 3 technology, as a result of its diachronic variability.
Other scrapers include the so-called "side scrapers." Most scrapers are either oval or blade-like in shape. The working edges of scrapers tend to be convex, and many have trimmed and dulled lateral edges to facilitate hafting. One important variety of scraper is the thumbnail scraper, a scraper shaped much like
In archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives , spears , axes , hammers , and maces .
A blade core becomes an exhausted core when there are no more useful angles to knock off blades. Blades can be classified into many different types depending on their shape and size. Archaeologists have also been known to use the microscopic striations created from the lithic reduction process to classify the blades into specific types.
