How should I care for the ito wrap and lacquer saya?
Updated Mar 2026
The blue ito cord wrapping requires minimal maintenance but benefits from occasional inspection for loosening at the knot points. If the wrap loosens over time due to humidity changes, a collector can carefully re-tension the cord without removing it entirely. Avoid exposing the handle to prolonged moisture, which causes the underlying rayskin or synthetic base to swell and distort the wrap geometry. The black lacquer saya should be wiped with a soft, dry cloth to remove dust and fingerprints - avoid water-based cleaners, which can dull or streak the lacquer surface. Storing the sword with the blade inside the saya, but removing it briefly every few months to air the interior, prevents moisture from becoming trapped against the blade finish.
