This axe is probably one of the cleverest, simple yet functional hafting designs of the Bronze Age.
It has the essential blade and septum details of the typical palstave but there is no stop ridge and the flanges have been exaggerated and  have been slightly folded by hammering into two pairs of curved wings.
Hammering has work-hardened the metal and given the wings a tough and tapering leaf spring character. 
The two fingers of the cleft forehaft driven down either side of the septum become wedged between the wings and the septum.
A chopping action wedges the forehaft even tighter into the wings. Binding is quite unnecessary.   Nevertheless, there is a small light loop.
At Hallstatt the miners used beech elbow crooks and formed the blade into the spike of a pick. 
They thinned the neck of the crook to give the beech a degree of spring.
