Fällkniven AB Swedish pronunciation: [ˈfɛlːkniːvɛn] is a Sweden-based manufacturer of knives and knife-related gear and apparel.
The Fällkniven model F1 has been the official survival knife for pilots in the Swedish Air Force since 1995.
Classified into a military-grade build, it boasts an ergonomic design, technical touch, and economical fabrication, which represent the top blend available in the market today.
In November 2000, the black versions of models F1 and S1 were tested and approved for use by air crews in the U.S. Marine Corps and U.S. Navy.
They met the requirements for function, design, strength and reliability of the Naval Air Warfare Center.
