Custom Made Damascus Lever Lock Auto Knife With Buffalo Horn Handle This Damascus Lever Lock Auto knife was created by forge welding multiple layers of steels into a Solid block called a billet (15N20 &1095 High Carbon Tool Steels). 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. When acid is added to the blade, it attacks the layers of hard and soft steels differently, highlighting the attractive layered pattern in the Steel.The combination of layered hard and soft steel creates blade flexibility, toughness and produces invisible serrations on the blade that aid cutting. The hardness of the Damascus steel is 55-60 HRC on Rockwell scale. The handle is made out of Buffalo Horn Handle, has a unique Hand Crafted . The spine of the blade is beautifully file worked. This knife comes with a genuine leather sheath, with a belt loop on one end. This knife is a must have for any Damascus Collector, hunter or outdoors-man! ***To prevent the blade from rusting, we recommend wiping the blade clean after use, and applying oil.*** SpecificationsOverall Length: 7.
