This neolithic axe blade or chisel was found in Northern China along with many other artifacts of neolithic origin. The axe is rather large measuring roughly 13 by 11 cm. and only about 5 mm. in thickness. The thickness of the blade is tapered from side to side and the bottom edge is finished to a sharp cutting edge. The most unusual aspect of this blade is perhaps the two holes. The Smithsonian (see below) has one example of a neolithic chisel with a second, unfinished hole. The stone is slightly calcified and the left edge still retains the tool's original finish.
