Catalogue entry no. 61 by Max Loehr:
61 Slendar Dagger-Axe
Mottled greenish gray jade with light markings and signs of incipient calcification. The blade is unusually slender and curves steadily toward its small tip. That the edges are set off by a step from the thicker central part of the blade is another unusual feature. This piece is distinguished further by a very long tang, which has a small hole drilled from the right side. Broken and repaired. Shang or Western Chou(?).
