Generally speaking it's an anticorrosion process. Gyokucho uses the latest chemical process to plate their blades with a micro-thin nickel coating. This is accomplished without the use of an electrical current, so the plating is a very uniform thickness. After being plated, the nickel plating enhances durability of the rust. The plating process produces such a smooth surface that adhesion of tree resins is greatly reduced and if occurs is easily washed from the blade with warm water. As you may know, rust is always a problem with steel products, particularly in humid and coastal areas. Gyokucho's Special Surface Treatment helps to prevent rust and tarnish.
