Catalogue entry no. 212 by Max Loehr:
212 Heavy Trapezoidal Knife with a Cutout
Bluish gray-green stone with dark gray veins and a few buff areas. Along the straight back is a row of four equidistant conical holes, drilled from the upper side, their lower edges left rough and unfinished. A fifth hole, drilled from the same side, is placed along the median axis farther to the right. Above this hole, the back shows a curved cutout similar to that in No. 211. The cutting edge is beveled on both sides and is blunt. Near the left tip, the edge cuts through a small perforation, which must have existed before the edge was fashioned. The upper left corner, which slants, remains in a raw state. Early Western Chou(?).
