How should I care for an engraved dragon blade on display?
Updated Mar 2026
Dragon-engraved blades require slightly more attentive maintenance than plain-ground surfaces because the recessed engraving channels can accumulate dust and trap ambient humidity if left untreated. Every four to six weeks, apply a small amount of choji oil or food-grade mineral oil to a soft, lint-free cloth and work it gently along the blade surface, paying careful attention to engraved grooves where moisture tends to settle. Wipe away any excess to avoid oil pooling in the scabbard or on wooden mounts. Store the piece horizontally on a proper sword stand in a stable, low-humidity environment away from exterior walls and direct sunlight. UV exposure is particularly damaging to lacquered saya, causing the finish to fade and crack over time. Avoid touching the blade surface with bare hands, as skin oils accelerate oxidation - use cotton gloves when handling the piece during repositioning or inspection.
