This biface is the seventh longest artifact in the Fenn cache. The many large percussion flake removal scars that can be seen on both sides are very impressive. This biface is described as being especially thin and the finishing work that was done to the edges may suggest that it was intended to be used as a knife. This biface is made of Green River Formation chert. It measures 8 1/16 inches (20.4 cm) long, 4 1/4 inches (10.8 cm) wide and 9/16 inch (13.9 mm) thick.
