Casstrom No.10 SFK Firesteel Knife

Casstrom No.10 SFK (Swedish Forest knife), Karelian curly birch, Sandvik 14C28N stainless steel

This excellent knife was created as a versatile knife for hunting, bushcraft, and general outdoor use. That is exactly what its name means – Swedish Forest Knife.

“Here at Casström, the No10 SFK is the first knife we designed and made, and it holds a special place in our hearts. It is even more satisfying to know that those who own and use it are just as attached to it! From the elegant, ergonomically designed Karelian birch handle to the strong and versatile blade, this is a knife that can skin a moose or split wood equally well. At Casström, we take pride in our attention to detail. Our knives offer custom-knife quality at a production price.”

The blade is 10 cm long, made from Swedish 14C28N stainless steel with a thickness of 3.8 mm, and heat treated to achieve a hardness of 57-59 HRC. The knife features a shaving-sharp Scandi grind and has a satin finish. This steel, combined with the grind, makes the knife very robust while still being easy to sharpen, which is a major advantage. The handle is made of Karelian curly birch. There are black liners between the handle scales and the steel to improve durability over time. The wood is treated with a traditional Scandinavian linseed oil-based finish. The knife comes with a sturdy 3 mm leather sheath featuring an extra-wide belt loop, a drainage hole, and a lanyard eyelet. The sheath includes a Firesteel ferro rod fire starter.
