thumb|Ameriški bojni nož ka-bar Bojni nož je borilni nož, ki se ga uporablja izključno za vojaško uporabo in je v prvi vrsti namenjen za goloroki boj ali pri boju iz bližine.Peterson, Harold L., Daggers and Fighting Knives of the Western World, Courier Dover Publications, , (2001), p. 80: "Right at the outset trench knives were introduced by both sides during World War I, so that the common soldier was once again equipped with a knife designed primarily for combat."Burton, Walter E., Knives For Fighting Men, Popular Science, July 1944, Vol. 145 No. 1, p. 150: A combat knife is specifically designed for military use, and is thus a more restrictive category than that of a fighting knife or tactical knife, either of which may include knives designed for civilian use. Thus, a bowie knife designed for civilian sale and use may be termed a fighting knife, but not a combat knife, while the U.S. Army's M3 trench knife, designed specifically for the military for close-quarters fighting, is both a combat knife and a fighting knife.Catalog of Standard Ordnance Items, Washington, D.C: U.S. Army Ordnance Publications (1943) Bojni oziroma vojaški noži se po koncu pozicijskih vojn sekundarno uporabljajo tudi za odstranjevanje listja, sekanje vej, odpiranje zabojev itd., zato se ga včasih prime ime "vojni-delovni nož".
