How should I store and maintain a teal cord tanto?
Updated Mar 2026
High-carbon and Damascus steel blades require routine maintenance to prevent surface oxidation. Apply a thin coat of choji oil or pharmaceutical-grade mineral oil to the blade every two to three months, or after any handling, since fingerprints transfer moisture and acids onto the steel. Store the tanto horizontally on a dedicated display stand or in its saya in a low-humidity environment — avoid basements or areas with temperature fluctuation. The teal ito cord wrap is sensitive to prolonged moisture and direct UV exposure, both of which can cause the color to fade or the cord to degrade. Keep the piece away from direct sunlight when on display, and never store it in an airtight bag, which can trap humidity against the blade.
