wood shaped knives
All wood processing and wood products manufacturing quality lie on the quality of tools. According to wood processing, our company has developed tools suitable for a wide range of materials research and development of special materials and the tools to creat new technology which is for special plywood process. Through the use of new materials and new technology, blades without oxidation of carbon steel and alloy tool steel welding tool possess wearable, sharp blade durable qualities.

Case hardening is a process of increasing the carbon content at the surface of very low carbon steel. It is done by placing the object to be hardened in a sealed container along with carbon-containing material; in antiquity, this material was usually horn or hide. The container would then be heated until it was glowing red, and held at that temperature for a while, based on the size of the part being hardened, allowing carbon to penetrate the steel by a few thousandths of a centimeter. At that point, the object would be dumped out of the container into a water bath to quench it, resulting in a very hard surface, but completely unhardened core. There is very little evidence of this having ever been done to swords except, perhaps, the very earliest of iron blades. Due to the inherent weakness of a sword's cutting edge, coupled with the high-impact stresses of combat, such a thin hardened surface over a soft core would provide very little advantage in terms of edge-holding, other than mild wear resistance.
