How should an Orange Damascus Steel Katana be stored and maintained?
Updated Mar 2026
For long-term display and preservation, Damascus blades benefit from a light application of choji oil or a neutral mineral oil on the blade surface every few months. This prevents surface oxidation and keeps the distinctive patterning clearly visible. The saya should be kept in a low-humidity environment; excessive moisture can affect both the wood or lacquer finish and the blade condition over time. When stored in the saya for extended periods, it is worth removing the blade periodically to ensure no moisture is trapped inside. For wall display, a horizontal or slightly angled mount away from direct sunlight is recommended — prolonged UV exposure can affect both lacquered finishes and wrapped handles. Handling the blade directly with bare hands should be minimized, as skin oils accelerate surface oxidation on polished steel.
