Folded steel refers to the repeated folding and forging of steel by manual hammer forging, so that the surface of the steel presents a pattern. It is a high-quality steel specially used for making swords. Many people have an obsession with folding steel, thinking that it must be better than non-folding steel. In fact, a quick fold without attention to detail can actually make the blade thinner. Coolkatana offers high quality folding steel katana. All are designed for practical use.
