closely resembles a machete or Filipino Bolo than a knife. In the United States Marine Corps, the standard issue combat knife since World War II has been the USMC Fighting Utility knife. Designed for military use, with input for Capt. George Ingraham, a combat surgeon in the U.S. Army's 94th Medical Detachment, the No. 14 Randall "Attack" Model was a popular combat knife designed for military use, and the knife was widely purchased by individual soldiers and Marines. During the conflict, Randall received feedback from Captain Ingraham, who requested serrations on the spine to cut through the fuselage of downed aircraft to rescue trapped personnel and a hollow handle to allow storage of survival gear. Randall made the changes and the result was the first of the modern survival knives. Another combat knife appearing during the Vietnam War was the Gerber Mark II, designed for military use by US Army Captain Bud Holzman and Al Mar which in turn was based on the pattern of a Roman Gladius or short sword. In the 1970s and 1980s a student and protégé of Fairbairn, Colonel Rex Applegate worked with knife designer Bill Harsey, Jr. to design the Applegate-Fairbairn Combat Knife, so named because it was designed as an improvement on the Fairbairn–Sykes based upon discussions Applegate and Fairbairn had during World War II to eliminate the weaknesses of the F-S knife (e.g., weak blade point, inability to determine orientation of blade merely by grip). The first of these knives were made by Al Mar Knives, based on Harsey's designs. Knifemaker Bill Harsey later teamed up with Chris Reeve to design the Yarborough Knife, a combat knife presented to each graduate of the United States Army Special Forces Qualification Course. In the latest step of this evolution, Bill Harsey and Chris Reeve have collaborated with the father of the Modern Army Combatives Program, Matt Larsen, to design the LHR Combat knife. The German military uses the Eickhorn KM2000 as their standard issue knife. The design is a westernized Tantō, issued to the Bundeswehr. The blade is made of either 440A or N695 depending on different models. Some of them use 55Si7 spring steel. The knifemaker Eickhorn in Solingen, Germany has issued KCB-77 bayonets to the Canadian Military and the USMC. Apart from the KM2000 there are many other knives from Eickhorn, the KM3000, KM4000, KM5000, ParaCommando, and Aviator Series knives. The knives from
