How should I display and maintain a collectible aikuchi?

 Updated Feb 2026

For display, a horizontal wooden tanto stand is the most traditional choice; it keeps the blade secure and shows off the saya's gray finish and any engraved or lacquered artwork. Avoid placing the piece in direct sunlight or near heat sources, as prolonged UV exposure can fade lacquer and dry out natural wood components like rosewood or sandalwood. For maintenance, apply a thin coat of choji oil — or any refined mineral oil — to the blade every four to six weeks to prevent surface oxidation, especially in humid climates. Use a soft microfiber cloth rather than abrasive material when wiping down fittings. If the saya has a lacquer finish, an occasional wipe with a barely damp cloth followed by immediate drying is sufficient. Proper care will preserve both the steel and the decorative elements for decades.
