White Deer Trailing Point Damascus Steel Hunting Knife Blank It features 5 holes on the tang for attaching your own custom handle, with each hole measuring appx 2.75mm. This is a beautifully crafted Custom Made Damascus Steel Hunting Knife blank for DIY and custom makers to add their own handle grip. Damascus for this knife 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 in the White Deer Trailing Point Damascus Steel Hunting Knife Blank 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 in cutting. The hardness of the Damascus steel is 55-60 HRC on the Rockwell scale. This is a must have for any hunter or outdoors-man!
