In the course of the Bronze Age metallurgical techniques and skills were developed which can hardly be matched today. The cone of the Berlin Hat, for instance, is beaten paper-thin from a single piece of gold and carefully shaped with a fine tool. Metalworkers in the Late Bronze Age possessed such fine, sophisticated tools. Among the contents of a hoard found near Murnau in Upper Bavaria was a small stake anvil and especially circular ribbed male (negative) and female (positive) punches just like the ones used for the circular patterns on the Gold Hat.
