Mottled brown stone with sparse, light gray markings. The flat faces widen slightly toward the straight, obtuse cutting edge; the blade becomes gradually thinner toward the bevels on either side of this cutting edge. At the butt, which is oblique, the faces slope asymmetrically inwards. Neat biconical perforation. Western Chou(?).
