This dataset consists of flake models representing an experimental archaeological reduction. This Core 3 Biface was knapped by Matthew D. Hunstiger. It and its related flakes are housed at the University of Minnesota's Department of Anthropology Evolutionary Anthropology Labs. These models are of the flakes that were created, or knapped off, as Hunstiger made that biface. They were created for the purpose of studying scar directionality in archaeological chipped stone analysis, and formed part of the experimental side of a dissertation by Matthew D. Hunstiger.
