The original of the DEGANWY early Bronze Age copper axe was found on the beach at the foot of the Great Orme, in North Wales, interestingly close to the Great Orme prehistoric copper mine.
However, the axe is not of local, Welsh copper but is of the type associated with Ballybeg/Roseisle, south west Irish copper.
These axes are characterised by their thin, narrow butt, often well arched, as in this example.
This is a short axe and so the convex curved sides splay quickly to the blade tips of the strongly curved cutting edge.
The  axe is 120 mm long and weighs 450 g. which is about as heavy as these early working axes could be made.
I have shown an example of how the head can be hafted in a yew haft, bound with wet rawhide, two ends working.
