Catalogue entry no. 214 by Max Loehr:
214 Fragment of a Trapezoidal Knife
Bluish gray-green stone with black and light brown markings. The blade, which is broken at the left end, has an irregularly curved back, a straight cutting edge, and an incompletely shaped right end. Three rather small conical holes along the back are drilled from the upper face; a fourth hole, also drilled from the upper face, is placed along the median axis to the left of the one farthest right. The bevels of the cutting edge begin with a sharply marked ledge, comparable to the bevels on No. 209. On the whole, this tool has a rather crude and unfinished appearance about it. Its material is the same, however, as in the exquisitely shaped shafted axe, No. 195, and the knife, No. 212. Early Western Chou(?).
