Kozuka

The kozuka is a small utility knife that was traditionally carried by the samurai class in feudal Japan. It was typically housed in a decorative sheath, often alongside a larger sword, and was used for a variety of practical purposes. These included tasks such as eating, grooming, and even as a secondary weapon in close combat. The blade of a kozuka is usually quite short, often less than four inches in length, and made from forged steel.

The handle, or tsuka, of the kozuka is a significant feature. It is typically made of wood and is often wrapped in rayskin (samegawa) and silk cord, similar to the handle of a katana. This wrapping provides a secure grip and prevents the hand from slipping. The pommel, or kashira, and the collar, or fuchi, which connects the handle to the blade, were often elaborately decorated. These decorative elements, along with the carvings on the metal casing that housed the blade (saya), showcased the craftsmanship of the period and the owner's status.

Kozuka were not mere tools; they were also artistic expressions. The metal fittings were frequently adorned with intricate designs, often depicting natural motifs like flowers, birds, or dragons, executed using techniques such as sukashi (openwork) or kebori (fine carving). While not as prominent as the samurai's primary weapon, the tanto, the kozuka played an integral role in their daily lives and served as a testament to their cultural and aesthetic sensibilities. Its presence signified preparedness and refinement.
