Lithic reduction involves the use of a hard hammer precursor, such as a hammerstone, a soft hammer fabricator, or a wood or antler punch to detach lithic flakes from a lump of tool stone called a lithic core. As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process. Lithic reduction may be performed in order to obtain sharp flakes, on which a variety of tools can be made, or to rough out a blank for later refinement into a projectile point, knife, or other object. Flakes of regular size that are at least twice as long as they are broad are called blades. Lithic tools produced this way may be bifacial or unifacial.
