Catalogue entry no. 22 by Max Loehr:
22 Disk-Axe
Fairly large, thin disk of opaque, ivory-colored jade with a sharp-edged, straight walled perforation. Two symmetrical, chordal cuts, converging upwards, have removed two segments of the disk. Along each of the edges so formed appears a set of six serrations. The arc below them has been ground to a sharpened edge, thus transforming the disk into an axe. The arc above the serrated parts was left blunt. Shang.
