Catalogue entry no. 41 by Max Loehr:
41 Heavy Dagger-Axe with Serrate Tang
Gray-green jade with lighter markings; some reddish earth and cinnabar remain on the left side. Well proportioned, smooth blade of exemplary workmanship. The crested blade is beveled along the upper and lower edges; the bevels end in a delicately ground, outward-curving ledge. The tip of the blade is not beveled but has sloping faces. The flattened tang is decorated with four pairs of teeth which project from the butt. A large conical perforation in the blade, drilled from the right side; two curiously placed similar perforations in the butt, one biconical and the other drilled from the left side. Shang or early Western Chou.
