Kukri, a broad-bladed, curved general-purpose cutting tool and weapon with Indian origins. In other countries the machete or Filipino Bolo were often used as fighting knives by indigenous military or paramilitary forces. Colonial powers that encountered these general-purpose weapons used as fighting knives during a military campaign occasionally adopted them in turn for use by their own military forces, as exemplified by the U.S. Army's Model 1910/17 "Bolo" brush-clearing knife, which would be later pressed into service as a fighting knife in both World Wars. In World War I, military use of the fighting knife saw the introduction of the "trench knife", a fighting knife designed solely for military use in the trench warfare of that conflict. On the Allied side, these "knives" were originally little more than sharpened spikes or cut-down bayonets fitted with handles. As the war progressed, French, British and U.S. ordnance branches began introducing fighting knives based on standardized patterns, such as the U.S. Mark I trench knife. In Western Europe, one dual-purpose fighting knife to be widely adopted by German forces during World War I was the Nahkampfmesser (Close Combat Knife), which despite its name was actually a general-purpose combat and field knife. The Nahkampfmesser was extremely popular in German military service, and would be issued again in slightly revised form during World War II as the Kampfmesser 42. World War II In the Pacific theater of World War II, U.S. Army and Marine Corps personnel frequently employed jungle and utility knives such as machetes, bush knives, hospital corps knives, and bolos as fighting knives. These knives were particularly favored by elite or specialist units such as the U.S. Army's Bushmaster regiment and Pioneer combat engineer detachment and the Marine Raider and Paramarine battalions of the U.S. Marine Corps. The success of these large knives in individual combat engagements caused authorities to reexamine the suitability of existing "commando"-type fighting knives for troops expected to fight the Japanese. In late 1942, the U.S. Marine Corps adopted the 1219C2, later designated the USMC Mark 2 Combat Knife or Knife, Fighting Utility, but better known in popular terminology as the KA-BAR. The KA-BAR differed from World War I-era U.S. fighting knives in that it was purposely designed as a dual-purpose weapon, adapted for both combat and as a utility knife. It also differed from some earlier USMC knives such as the Marine Raider stiletto in that the new
