A well-maintained sword will retain its appearance and reduce the risk of oxidation over time. A few simple steps are enough to preserve it, whether it is intended for collection, decoration, or ceremonial use.
After each handling, wipe the blade with a soft, dry cloth to remove fingerprints. Sweat naturally contains moisture and salts that can promote the appearance of stains or corrosion, especially on carbon steel blades. If your sword is made of carbon steel (such as EN45, 1045, 1060, or 1095 steels), regularly apply a very thin layer of protective oil using a clean cloth.
A neutral mineral oil or an oil specially designed for antique weapons works perfectly. There is no need to apply much: a light protective film is sufficient. Always store your sword in a dry place, away from extreme temperature changes and humidity. If it is kept in a leather sheath, it is best not to leave it inside permanently, as leather can retain moisture and tannins that may damage the blade over time. Finally, avoid abrasive products, steel wool, or harsh cleaners that could damage the polish or engravings.
If slight oxidation marks appear, a product specifically designed for blade maintenance will usually remove them easily. With regular care, a quality sword can maintain its shine and original condition for many years.
