Kai Simonsen and Gerhard Munz have worked together as friends for more than three decades. The fusion of their areas of expertise, wood and steel, symbolized in the logo through tree and anvil, led to an entire line of well-designed products, such as the drums and the award-winning door handles. In 1989, they organized their first joint drum building workshop.
Gerhard Munz passed away in August 2011. Ever since then, Kai Simonsen has continued to developed new products on his own.
