How should I store and care for a display tanto long-term?
Updated Mar 2026
Carbon steel tanto — including T10 and Damascus variants — will develop surface oxidation if left unprotected. For long-term display, apply a thin coat of choji oil (a traditional clove-oil blend) or a light mineral oil to the blade surface every two to three months, wiping on with a soft cloth and buffing off any excess. Store the tanto horizontally on a dedicated stand or resting edge-up in the saya, away from humidity and direct sunlight. Lacquered saya can be wiped clean with a dry cloth; avoid water contact on the lacquered surface. Rayskin-wrapped handles require no special maintenance beyond keeping them dry. When handling, use cotton gloves to prevent skin oils from accelerating corrosion on polished steel.
