Notes on Uniface Retouch Technology

The repeated occurrence of flakes possessing remnants of unifacially trimmed edges was noted in the analysis of chipping refuse from two late prehistoric sites in west central Texas. Attributes on these flakes suggest three techniques of removal–by a burin technique, by striking the uniface on the ventral surface near the edge, and by striking the uniface on the dorsal surface near the edge. Examples of these retouch techniques were evident on certain unifacially chipped scrapers from the two sites, and, together with wear patterns and edge angle values, support inferences that the flakes are by-products of uniface retouch.
