What does the dark blue ito wrapping actually consist of?
Updated Mar 2026
The ito — the cord wrapped around the tsuka — on these wakizashi is executed in a deep indigo cotton or silk material, depending on the specific piece. Beneath the wrap sits the same, the textured ray skin panel that provides both an authentic surface detail and a foundation for the diagonal hishigami paper inserts that shape each diamond of the wrap pattern. The alternating over-under tension of the wrap is what gives the tsuka its characteristic diamond grid appearance. Indigo and dark blue ito has historical precedent in Japanese sword fittings, where specific colors were associated with particular schools or status conventions. For display collectors, the deep blue tone creates a strong contrast against gold or black tsuba and anchors the overall koshirae color palette effectively.
