How should I store a clay tempered tanto for long-term display?
Updated Mar 2026
Clay tempered high-carbon blades require more attentive storage than stainless alternatives. The primary concern is moisture — high-carbon steel will develop surface oxidation if exposed to humidity without a protective oil coat. Before placing a tanto in its saya for display or storage, apply a light coat of choji oil or a suitable mineral oil to the blade using a clean, lint-free cloth. The saya should be made of wood (as is standard in this collection) rather than synthetic materials, since wood allows minor humidity fluctuation without trapping moisture against the blade. Avoid storing in environments with wide temperature swings or direct sunlight, which can affect both the lacquer on the saya and the blade's surface. A monthly inspection and re-oiling schedule is sufficient for most indoor display conditions.
