Handle / HandleEk with black shims
Case / holsterDeep knife blade in thick vegetable tanned leather
The blade is about 10 cm long and manufactured in about 3.8 mm thick O2 tool steel (Böhler K720) with high carbon content which is heat treated to achieve a hardness of 58-60 HRC. The knives are sanded with Scandinavian grinding and have a silk mat finish. This steel in combination with the taper grinding makes these knives very impact resistant, even in cold conditions, retains sharpness but is very easy to sharpen and they can get a very sharp edge relatively easily.
The handle is made of oak. Between the scales and the steel are black liners to increase durability over time. The handle is mounted with sturdy brass rivets. The wood has been treated with a traditional Scandinavian linseed oil based blend. The knife comes with a very sturdy brown knife case made in 3 mm thick vegetable tanned leather. The knife sheath has an extra wide belt loop, an opening in the bottom for liquid and a hole for an anchorage strap.
About the Steel - O2 Tool steel
This tool steel from Böhler (K720) is a very strong oil hardened tool steel with high carbon content. The chemical composition allows it to harden to a high hardness with retained ductility and toughness while being easy to grind and can obtain a very sharp edge that holds well. This steel is a low-chromium carbon steel that will rust if left wet and must therefore be dried after use and protected with oil or wax when the knife is stored in a high humidity environment.
