This Georgetown flint Kerrville biface was made by an anonymous American flintknapper after ca. 1990.
The tool in this model was made to mimic a Kerrville biface. It was artificially patinated to make it look ancient. However, small smears of copper are present on remnant platform indicating that it was made using a copper ‘bopper’ percussion-flaking tool. Copper boppers proliferated among hobbyist flintknappers from about 1990. Kerrville bifaces—also called ‘fist axes’, ‘carcass cleavers’, or ‘butted bifaces’—are found in the Late Archaic period in Texas, ca. 2300-2650 BP. They often have glossy use-wear on the edges from cutting meat or soft plants. Kerrville bifaces were resharpened bifacially as they were used, sometimes creating deep convex edges. The morphology of an unfinished cortical base—to protect the hand—and a triangular bifacially-flaked distal end is reminiscent of a certain variety of Acheulean handaxe. The Kerrville biface demonstrates convergence on an ancient tool tool design by Native American flintknappers. The modern-made Kerrville biface in this model closely matches the ancient example illustrated in the book Stone Artefacts of Texas Indians.
