How should I store and maintain a Sakabato display piece?
Updated Feb 2026
Carbon and manganese steel blades require regular maintenance to prevent oxidation, even when kept indoors. Apply a light coat of choji oil or mineral oil to the blade surface every one to three months, depending on your local humidity. Store the sword horizontally on a display stand or inside its saya with the edge — on a Sakabato, the spine side — facing upward, which is the traditional orientation for katana storage. Avoid areas with large temperature swings or moisture fluctuation. Never store a blade in a leather-lined case for extended periods, as leather retains moisture. When handling, use a clean cloth or cotton gloves to prevent fingerprint acids from contacting the steel.
