How should I store a red handle wakizashi to preserve the ito?
Updated Mar 2026
Store your wakizashi horizontally in a padded display case or on a proper sword stand, away from direct sunlight, which can fade red ito over time regardless of material. Humidity is the primary enemy of both the handle components and the lacquered saya — aim for a stable indoor environment between 40–60% relative humidity. Apply a light coat of choji or mineral oil to the blade every few months to prevent surface oxidation, and avoid touching the blade surface with bare hands, as skin oils accelerate patina formation. The saya should be removed periodically to ensure no moisture is trapped against the blade.
