Use fine quality materials, forged clamp steel, and the material has been subjected to vacuum cryogenic heat treatments, you can use it to make the cutting tools you want, come on and try it. Features: Use fine quality materials, forged clamp steel, higher density and toughness, and durable-sharpness for cutting tools. The material has been subjected to vacuum cryogenic heat treatments, and the hardness on both sides is slightly lower, and it has the characteristics of sharpness and toughness. Use some necessary tools such as grinder or angle grinder for DIY. The material undergoes flat grinding and simple pickling, but it need be pickled again after molding/opening. The patterns on both sides of the product may have different textures and thicknesses due to forging. The steel will be slightly stressed and deformed during the heat treatments process. You can directly use a hammer to straighten it, because the steel plate has high toughness on both sides, which is the characteristic of all pattern steel blanks. There are four patterns to choose from, you can choose the pattern you like. Specifications: Material: steel HRC58°±1 Type:(optional) Type1: herringbone pattern Type2: spiral pattern Type3: water-wave pattern Type4: cloud pattern Item size: 100 * 30mm / 3.9 * 1.2in Package size: 100 * 30 * 2.5mm / 3.9 * 1.2 * 0.1in Package weight: 70g / 2.5ounce Note: Due to forging and cutting, there will be a thickness error of 0.1mm~0.2mm.
