What are the advantages of handmade iron

Shapes can be customized and sizes can be controlled with precision. Forged steel structure is more compact, less impurities. For example, after stacking and beating jade steel, the carbon content is uniform, and the surface of the knives made by polishing has a beautiful ground muscle texture, and the same is true for Damascus patterned steel. Handmade can also do special heat treatments, such as overlay burnishing, layered quenching, and pickling. Such hand processes can give a piece of steel different hardness and flexibility in different parts. In the case of knives, hand forging can also create a sandwich of steel bars, the outer hard high-carbon steel skin, the inner core of flexible manganese steel and flexible, bending 60 degrees can be bounced back to its original position.
