How do I prevent the black lacquer on a tanto sword scabbard from fading?
Updated Feb 2026
Black-lacquered saya are durable and hold their finish well with basic care. The primary enemy of lacquer is prolonged UV exposure, which can cause fading and eventually cracking over time. Display your black tanto sword away from windows or direct sunlight, or use a display case with UV-filtering glass if the room receives significant natural light. Dust the saya periodically with a soft, dry cloth. If fingerprints or light smudges appear, a slightly damp microfiber cloth will clean the surface without affecting the lacquer. Avoid using chemical cleaners or solvents on lacquered wood. For the blade itself, maintain the standard oiling routine with choji oil every few months to keep the steel surface protected.
