What maintenance does a Chinese dao sword require compared to a Japanese katana?
Updated Feb 2026
A Chinese dao sword in carbon steel or Melaleuca folded steel requires essentially the same maintenance routine as a Japanese carbon steel katana. The primary care task is preventing surface oxidation: wipe the blade after handling with a soft dry cloth to remove fingerprint oils, and apply a light protective coat of neutral oil - choji oil, camellia oil, or a similar sword-care oil - every two to three months using a soft cloth applied from the base of the blade to the tip. Store the sword in its scabbard in a stable indoor environment away from direct sunlight and moisture sources. The wooden scabbard of a Chinese dao, like the saya of a Japanese katana, protects the blade from dust and incidental contact. The carved wooden handle fittings on most dao are treated wood rather than wrapped cord, which requires different care: avoid water contact on the carved wood, and if the wood appears dry after extended display, a very thin application of natural wood oil to the handle exterior addresses it. With this basic routine, a carbon steel dao maintains its appearance and condition reliably.
