Palstave axes refers to the group of axes, used in the Middle Bronze age, that were flat, flanged and attached to a wooden haft via the butt end. They did not have a socket. Their evolution progressed to include a small suspension loop from which twine or hide was attached to wrap around the haft. Within the category there were various examples and artistic license. Some axes feature a stop-ridge, for the wooden haft. Others, like this example, did not and instead the flanges were folded over to secure the haft in place. This variety was more common in France and Germany as opposed to England.
