Tsuka Wrapping Shim Paper for Samurai Sword

Tsuka Shim Paper (詰め紙 / Tsume-gami) for Katana, Wakizashi, and Tanto

Tsuka shim paper refers to the paper used during the construction and wrapping of a Japanese sword handle (tsuka). It is placed between the wooden handle core (tsuka core) and the handle wrapping (tsuka-ito) to act as a shaping and cushioning layer.

These paper shims help refine the geometry and thickness of the handle, providing a stable foundation for the tsuka-ito during the wrapping process. By allowing the wrap to be tightened evenly and securely, tsuka shim paper helps achieve a firm, uniform handle wrap.

Proper use of shim paper improves the overall stability of the tsuka assembly, reduces the risk of the wrap loosening over time, and enhances both grip comfort and durability.
