Start by regularly cleaning the blade with a soft, dry cloth to remove moisture and prevent rust. For deeper cleaning, use a mild oil to maintain the metal’s luster. Store the sword in a dry, cool environment, ideally in a protective sheath or display case to avoid dust and accidental damage. Avoid exposing the sword to extreme temperatures or humidity. Regularly check for any signs of wear or corrosion and address them promptly to ensure the longevity and effectiveness of your prized piece.
