How should I store a white handle ninjato to keep the tsuka clean?
Updated Mar 2026
White ito and pale tsuka materials are more susceptible to visible discoloration from skin oils, humidity, and dust than darker wraps. For long-term display, keep the sword horizontal on a proper katana stand in a low-humidity environment - ideally between 40-50% relative humidity. Avoid direct sunlight, which can yellow white ito over time. When handling, use clean cotton gloves to prevent skin oil transfer. The blade itself should be lightly coated with choji oil every few months to prevent oxidation, applied with a soft cloth and wiped to a thin, even layer. Keep the saya fitted when the piece is not being actively viewed to protect both the blade finish and the interior lacquer from dust accumulation.
