Catalogue entry no. 46 by Max Loehr:
46 Small Dagger-Axe with Grooved and Crenelated Tang
Ivory-colored opaque jade, with cinnabar stains on the right face of the blade. This blade shows several unusual features: a symmetrical outline and symmetrical bevels; a straight median ridge; deeply hollow-ground faces; and finally, blunt edges and a blunt point. Near the base of the blade is a slanting, conical bore-hole, drilled from the left side. The tang is transformed into a sharply cut set of five ribs with lateral grooves; the sunken interstices are ground down to form gentle slopes toward the butt, where they end in four deep, angular recesses. Late Shang or Western Chou.
