How should I care for the lacquered saya on a silver katana?
Updated Mar 2026
The lacquered saya on a silver manganese steel katana requires different care than the blade itself. Avoid storing the sword in the saya for extended periods - trapped moisture between blade and saya interior accelerates oxidation on the steel and can soften or crack the lacquer liner. For the exterior finish, wipe with a soft, dry microfiber cloth to remove fingerprints and dust; avoid any solvent-based cleaners that can strip the lacquer's sheen. Keep the piece away from prolonged direct sunlight, which causes silver lacquer to yellow noticeably over months. For the blade itself, a thin coat of choji oil or food-grade mineral oil applied every two to three months provides adequate protection in most indoor environments.
