The Gerber LHR Combat Knife is an urban warfare close quarter combat knife. After studying and interviewing hundreds of real life hand-to-hand combat encounters, MACP Close Quarter Combat expert Matt Larsen worked with award-winning knife makers Chris Reeve and William W. Harsey Jr. to create the L.H.R. This big, solid combat knife is perfect for urban situations. The quick-release sheath has a built-in safety release that can only release the knife by the wearer.
