WILLUMSEN PORTFOLIO
Five disciplines. One studio. Built in Copenhagen for the people who use their tools.
-
UNIQUE
Knives designed with intent. Built for purpose. Made to outlast trends, owners, and fashion.
-
CUSTOM
From sketch to steel. We turn your brief into a finished tool — proven by global launches that started exactly the same way.
-
CRAFT
Precision tools for people who get paid by the result. Durable. Dependable. Built to be the last one you buy.
-
MULTI
One tool. Many jobs. Compact enough to carry, capable enough to count on — engineered for the way you actually work.
-
COLLAB
We co-create with brands that take their craft as seriously as we take ours. Your name. Our design discipline. A product that earns both signatures.

PACKAGING
Sustainability meets elegance
We design our packaging the same way we design our tools — to earn every gram, every fibre, every detail.
Responsible materials. Considered construction. Nothing wasted. The box is built to protect the product in transit, present it like it deserves on arrival, and stay useful.
Open it once for the unboxing. Keep it for the storage. Pass it on when you upgrade. The packaging is part of the product — not the part you throw away.
Exceptional tools deserve exceptional presentation. Every single time.

Today, Willumsen has evolved into a tool and knife design company that extends beyond its original focus on custom knives to encompass a diverse range of everyday tools and cutting accessories.
