Willumsen graduated from the College of Arts and Crafts, Wood and Interior Department in Kerteminde in 2000. All his knives are manufactured in his own workshop. He seeks inspiration from many places, often from nature and he uses materials as for example high quality steel, carbon fibre, fibreglass, titanium, bronze, silver and wood for the design of his select knife series. He requires his knives to be durable with an exclusive look. He considers the knife to be a per-sonal tool that must be able to last all life!
