How should I care for and display these anime sword replicas?
Updated Feb 2026
Carbon steel is susceptible to surface oxidation, so a light application of choji oil or mineral oil along the blade every four to six weeks will maintain the polished finish and prevent rust spots. Use a soft microfiber cloth rather than abrasive materials to avoid scratching the hamon line. Store or display the swords in a climate-controlled room with moderate humidity — avoid basements, garages, or areas near heating vents that cycle between damp and dry conditions. For wall display, a horizontal katana rack with padded cradles protects the saya's lacquer from scuffing. If you keep a sword inside its cloth bag for extended storage, include a small silica gel packet to absorb residual moisture.
