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 the extensive field tests conducted during both hot summer days and freezing cold winter nights was an advanced, well-designed, and safe knife where strength and modern design go well together. Its great popularity in the civilian market is a testament to its incredible versatility. The combination of tough, laminated specialty steel and a secure grip is attractive to most! Many are extremely satisfied with this knife, which has over the years become something of a signature for our company. Is there a better knife in this size? Military users generally dislike shiny knives, which is why we offer the F1 with a black blade. The surface consists of CeraCote 8H and adheres well, though not permanently.
