How should I maintain a Sanemi Sword on long-term display?
Updated Feb 2026
Long-term display maintenance for a 1045 carbon steel replica focuses on two main concerns: oxidation prevention and handle preservation. For the blade, apply a thin, even coat of choji oil (traditional Japanese sword oil) or a neutral mineral oil every two to three months. Wipe off any excess with a soft cloth to avoid pooling near the habaki (blade collar) or inside the scabbard. Store the sword horizontally on a katana stand in a stable environment - aim for moderate humidity between 40-60% RH and keep the blade away from direct sunlight, which can fade both the blade's finish and the ito cord wrapping on the handle over time. Remove the blade from the scabbard periodically to allow air circulation and inspect for any early signs of surface discoloration.
