Silk braiding around this scabbard is designed to prevent the expensive lacquer from rubbing against a warrior’s armour. An elegant crystalline structure appears on the blade in a pattern known as ‘drifting sand’ (sunagashi). This effect is produced during the tempering process, when the blade is rapidly heated and then cooled to achieve a resilient core with a hard outer edge.
