What is the difference between piano lacquer and matte hardwood saya finishes?
Updated Mar 2026
Piano lacquer saya are finished with multiple coats of high-gloss lacquer, then polished to a smooth, reflective surface that resembles lacquerware in traditional Japanese craft. The finish is visually striking and protects the underlying wood from minor moisture exposure, but it is more susceptible to surface scratches and should be stored away from hard surfaces and direct sunlight, which can cause the topcoat to craze over time. Matte hardwood saya use an oil-rubbed or low-sheen finish that absorbs light rather than reflecting it, giving the katana a more subdued, classic appearance. Matte finishes tend to be more forgiving of minor contact marks and are often preferred by collectors displaying multiple pieces together, as they reduce visual competition between blades on a shared stand.
