What makes the white and black tsuka wrapping distinctive?
Updated Mar 2026
The white and black color pairing on a tanto handle — known as the tsuka — comes from alternating ito (braid) wound over samē, the textured ray skin underlayer that provides grip surface and structural padding. Unlike single-color wrappings that blend into the overall finish of a piece, the high-contrast white-black combination creates a strong visual rhythm along the handle, emphasizing the diamond-shaped gaps in the binding where the samē shows through. Historically, this contrast palette was associated with formal presentation pieces where visual clarity and aesthetic deliberateness mattered. For collectors, it also functions as a reliable indicator of how carefully the rest of the mounting was considered — a maker willing to invest in precise two-tone wrapping is typically attentive to fittings alignment and overall finish quality as well.
