This picture shows a very close up view of the best preserved end of the billet/burnisher from the Blackwater Draw locality No. 1 site. The surface is slightly convex and the edges are fairly sharp and well defined. Although it has obviously experienced some surface distortion before the effects from drying were halted by preservation and restoration processes. Agogino and Haynes concluded at the time of its discovery that the smoothness of this end indicated that it was used as a polisher possibly for leather. It measures approximately 1 13/16 inches (4.6 cm) wide and 1 5/16 inches (3.48 cm) thick.
