knife used a stout, wide blade with clip point that facilitated slashing attacks as well as blade thrusts. Subsequent reports on the effectiveness of the new knife in jungle combat substantiated the Marine Corps decision to standardize the KA-BAR as the USMC's fighting knife for individual Marines. In contrast, in 1941 Great Britain introduced one of the most famous "pure" fighting knives designed specifically for military use in combat, the British Fairbairn–Sykes fighting knife (F-S). A traditional single-purpose fighting knife, with an acutely pointed, stiletto-type blade designed to emphasize thrusting strokes (puncture wounds), the F-S was based on the concepts and ideas of William E. Fairbairn and Eric A. Sykes, two renowned former members of the Shanghai Municipal Police who trained countless soldiers in the art of close-quarters fighting. The Fairbairn–Sykes knife inspired several similar knives of the era such as the V-42 stiletto designed by Lt. Colonel Robert T. Frederick, who commanded the joint US and Canadian First Special Service Force and the Marine Raider stiletto designed by Lieutenant Colonel Clifford H. Shuey. Capt. Fairbairn would later introduce a much larger fighting knife, the Smatchet, based on the traditional Welsh Fusiliers trench knife of World War I. The U.S. Army adopted the M3 Fighting Knife in 1943 as its standard fighting knife. The M3 replaced the earlier World War I-vintage Mark I trench knife in combat service. The M3 was designed primarily designed as a purist fighting knife, though some compromises were made in the design to conserve strategic materials. When adapted to utility tasks such as opening ration tins or ammunition boxes, the limitations of the M3 pattern quickly became apparent. In the United States, Knifemaker Bo Randall began production of the "All Purpose Fighting Knife" giving it the designation of "Number 1" in his catalog. Between 1942 and 1945, Randall Made Knives produced 4,000 of these knives for battlefield use by US troops, with approximately 1,058 knives additionally subcontracted to another firm to meet wartime demand. In the 1950s Randall would adopt the general pattern of the Bowie knife for several of his fighting knife designs. Post-WWII to present Designed for military use, Bo Randall's No. 14 "Attack" Model was a popular fighting knife used after World War II. During Vietnam, Randall received feedback from Captain George Ingraham, a Combat Surgeon in the US Army's 94th Medical Detachment. Ingraham's request was for serrations on the spine to
