1、Use fine quality materials, forged clamp steel, higher density and toughness, the cutter you making will has a longe using time and sharpness. 2、You need to working with some necessary tools such as grinder or angle grinder for DIY. 3、The material undergoes flat grinding and simple pickling, but it need be pickled again after molding/opening v. 4、The patterns on both sides of the product may have different textures and thicknesses due to forging. 5、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. Do you want to try to make a cutter by yourself? you can try this product. Use fine quality damascus steel 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, it will not let you down.
