Edge beveling of bifacial knives is well illustrated in this drawing. Specimen b is a "two-bevel form" and c-d are "four-bevel forms." Item i is a biface in an early stage of use, suggesting what the original size and shape might have been before successive edge use-wear and resharpening processes reduced the overall size and caused edges to become increasingly beveled or angled. Beveling is a process of tool resharpening without significantly reducing the size of the artifact. Item g is a simple cutting tool made on a flake. (Size ½; drawing from Krieger 1946, Figure 7.) |
