Clouded but translucent light green jade with amber-to-brown veining, this blade has polish leaves surface and edge pitting. The long trapezoidal blade shows an early unevenness of form, partly invaded now by clacification. A slightly concave cutting edge was bevelled to extreme thinness from one side only. The 4 conical perforation, displaying three in the row along the backing while the other near the tip to the center were drilled alternating from the obverse or beveled face and reverse.
