Compare two examples from the Winthrop collection, illustrated by Loehr in Ancient Chinese Jades, Harvard University, Massachussets, 1975, nos. 73 and 74, p. 76, which have similarly shaped jade dagger mounted on turquoise-inlaid bronze shaft. The jade blades of the Winthrop examples, however, are not drilled, and there is an extra bronze section between the end of the blade to the hand guard. It is possible that on the current piece this section was damaged, as there are signs of restoration at the join of the jade blade and the shaft. Compare also a jade blade excavated from the tomb of Lady Fuhao (fig. 1), with very similar proportion to the present jade dagger and the blade drilled with a large hole.
