Marble-lacquered saya are more durable than raw wood but still benefit from mindful handling. Avoid placing the scabbard in direct sunlight for extended periods, as UV exposure gradually fades pigmented lacquer. After handling, wipe the surface with a soft, lint-free microfiber cloth to remove oils and fingerprints. If the finish ever looks dull, a tiny amount of Renaissance wax buffed lightly across the surface restores its depth without leaving a sticky residue. Never use alcohol-based cleaners, which can dissolve or cloud the lacquer layers. Store the tanto horizontally on a padded stand in a room with stable humidity, ideally between 40 and 60 percent, to prevent the wood core from expanding or contracting under the lacquer.
