How should I store and maintain these carbon steel replicas?
Updated Mar 2026
Carbon steel requires more mindful care than stainless, but the routine is straightforward. After any handling, wipe the blade with a clean microfiber cloth to remove fingerprints, then apply a thin layer of choji oil or food-grade mineral oil along the entire flat to inhibit oxidation. Store the sword horizontally on a dedicated katana stand - vertical storage in the saya for extended periods can trap moisture. Keep the display area away from direct sunlight, which fades lacquered saya finishes over time, and avoid high-humidity environments. If you attend conventions or handle the piece regularly, cotton gloves prevent skin oils from etching the blade surface. With this basic routine, your replica will hold its display condition for many years.
