I believe the term ‘one of a kind’ is the most appropriate to describe Det Tidkun’s work because he only makes one prototype of each of his knives. Made as a super-limited-edition, the Behemoth is one of Tidkun’s many knife designs that get showcased and finally sold on his Etsy page under the moniker Ironbone knives. A craftsman from Thailand, Tidkun makes all his knives by hand, only using power tools to craft and grind billets of steel down to the final product.
