The tool consists of a rounded stone struck a
number of blows with a similar stone used as a
pounder,which created a serrated crest that served
as a chopping blade

A hand axe is a prehistoric stone tool, bifacially
worked (meaning it has two faces) and roughly
teardrop-shaped

Cleavers are large, oblong or U-shaped stone tools,
similar to hand axes but distinguished by their wide,
straight cutting edge.
