WHITE DEER Champion Karambit Knife Magnum Karambits are highly developed and useful for quickly cutting or slicing, plus the forward curve of the blade is perfect for cutting off a seatbelt, strap, or rope in an emergency situation. Some Martial Arts are dedicated to the focus of use of a Karambit knife. Damascus for this WHITE DEER Champion Karambit Knife Magnum was created by forge welding multiple layers of steel into a solid block called a billet (15N20 & 1095 high carbon tool steel). The billet is folded and re-welded several times to produce several layers. Patterns are created by manipulating the steel during the forge welding process. The darker steel is a stable oxidation of the 1095 high carbon steel and the lighter color steel is the 15N20 alloy steel. The combination of layered hard and soft steel creates blade flexibility, toughness and produces invisible serrations on the blade that aid in cutting. The hardness of the WHITE DEER Champion Karambit Knife Magnum blade is 55-60 HRC on the Rockwell scale. Comes with a genuine White Deer leather sheath featuring a snap retention and belt loop. Each piece is made by hand to White Deer Perfection.
