Tsuka-shi and Menuki-shi: The Craftsmen Who Create the Miniature Worlds in Your Hand

The Anatomy of a Handle

A Japanese sword's tsuka (handle) appears simple but is a precision craft object combining components from multiple specialists: the tsuka-gi (wooden core), same (ray skin covering), menuki (decorative side ornaments), fuchi (collar at guard end), kashira (pommel cap), and tsuka-ito (handle wrapping cord).

The Tsuka-shi: Wood and Ray Skin Expert

The handle maker shapes the ho (magnolia) wood core to match the nakago precisely — a process called hiyose — then applies ray skin (despite the name "same" meaning shark, genuine same is manta ray skin) with the central large granule positioned for maximum aesthetic effect and grip. Lacquer-based adhesive ensures permanent uniform adhesion.

The Menuki-shi: Miniature Sculptor

Menuki are 3–5cm decorative ornaments mounted on both sides of the handle. Despite their tiny size, the craftsmanship applied is breathtaking. Subjects range from dragons, tigers, and waves to family crests and seasonal motifs. Materials include gold, silver, shakudo (copper-gold alloy), shibuichi (copper-silver alloy), and brass. Casting followed by chasing and engraving is standard; high-quality pieces feature fully three-dimensional takabori relief carving and inlay (zoogan) of contrasting materials.

The Tsukamaki-shi: Thread Tension Artist

Handle wrapping requires threading silk, cotton, or synthetic cord over the ray skin while strategically positioning the menuki for grip. Standard wrapping methods include moroyon-maki (twisted double-cord standard), jabara-maki (accordion pattern), hira-maki (flat cord parallel), and tsumami-maki (pinched decorative). Evaluation focuses on uniform tension, menuki placement, and rhombus geometry consistency. Even skilled practitioners spend several hours wrapping a single handle.

Unified Design: The Collaboration Goal

When tsuka-shi, menuki-shi, fuchi-kashira-shi, and tsukamaki-shi each execute their specialty at the highest level — and when the resulting pieces harmonize in material, theme, and color — the complete koshirae emerges as a unified work of collaborative artistry.
