How should I store and maintain a Damascus tachi on display?

 Updated Mar 2026

Damascus steel is more reactive to humidity than monosteel blades because the folded layers can develop micro-surface variation that traps moisture. For long-term display, keep the sword in a climate-controlled room with relative humidity between 40% and 55%. Apply a thin coat of choji oil or a purpose-made blade oil to the entire surface every two to three months, wiping away any excess with a clean lint-free cloth. Avoid touching the blade directly with bare hands - skin oils accelerate surface oxidation. Store the sword in its saya when not actively displayed, and if using a horizontal wall mount, ensure the edge faces upward to prevent oil from pooling unevenly along the hamon area. Remove the blade from the saya entirely once or twice a year to check for moisture trapped at the habaki collar.
