Stainless Steel Swords Stainless Steel is one of the most common metals used in high quality cutlery today. It has the desired flexibility and hardness required to handle tough treatment and keep an edge. With stainless steel, one must be more cautious because the evidence of corrosion does not show itself as quickly as it does on carbon steel. If there is bronze on the handle, you should put a light coat of oil or grease on it to protect it from deep tarnishing. However, the blade will not easily rust.
Stainless steel can rust if it is in direct contact with water.
But it is easily polished away and restored to its original shine. Preventive maintenance should be used as described for the carbon steel swords, however you may choose to use a good metal polish periodically. Blades Cast steel and alloys are used on decorative or theatrical swords. Cast steel is not flexible like forged carbon steel or stainless steel. That means you cannot bend the blade back and forth.
