Definition and Purpose
A shirasaya (literally "white scabbard") is a simple, unfinished wooden mounting for a Japanese sword blade, consisting of a saya (scabbard) and tsuka (handle) made from magnolia wood (honoki) or similar materials. Unlike decorative mountings called koshirae, a shirasaya has no lacquer, metal fittings, tsuba (guard), or cord wrapping. Its primary purpose is long-term storage and preservation, protecting the blade from humidity, oxygen, and other environmental factors that can cause rust or corrosion.
