It took eight years to develop model F1, a knife that is now used as a survival knife within the Swedish Air Force. The result of extensive field tests conducted during both hot summer days and icy cold winter nights was an advanced, well-designed, and safe knife where strength and modern design blend well together. Its popularity in the civilian market testifies to its tremendous versatility. The combination of tough, laminated special steel and a secure grip is appealing to most! Many people are extremely satisfied with this knife, which over the years has become somewhat of a hallmark for our company. Is there a better knife in this size? Military users often prefer that their knives do not shine; for this reason, we offer the F1 with a black blade. The surface consists of CeraCote 8H and adheres well, although not permanently.
