How do I properly store and maintain a display tanto?
Updated Mar 2026
Maintaining a display tanto is straightforward but requires consistency. The blade should be lightly coated with a thin layer of choji oil or mineral oil every two to three months to prevent surface oxidation, particularly in humid climates. When applying oil, use a clean, lint-free cloth and work from the base toward the tip in single strokes — never wipe back and forth, as this can introduce micro-scratches to the polished surface. Store the tanto horizontally on a dedicated blade stand or within a sealed display case away from direct sunlight, which can fade lacquer finishes on the saya over time. Avoid storing the blade inserted in the saya for extended periods without occasional air exposure, as trapped moisture can affect both the steel and the interior lining.
