A tool in green stone with paler patches. The outline is asymmetrical and roughly rectangular with two of the sides forming a continuous curve, a third a relatively straight section and the fourth roughly broken. The cross-section is an irregular quadrangle. One face is flat and polished with a facet at the top, the other is flat and polished with three sides rounded and ground. There is no evidence of a cutting edge, although the straight side has a sharper central ridge, probably left by sawing. There are fine fractures around the edges.
