Catalogue entry no. 25 by Max Loehr:
25 Chisel
Light milky brown stone with a few darker veins. The blade, its thickness diminishing almost imperceptibly toward the double-beveled cutting edge, has straight sides and a nearly straight butt. Below the butt are two conical perforations, a small one above it, and a large one below it, both drilled from the upper side and aligned to the median axis. Shang or Western Chou.
