The Ko-Tosho style of Tsuba first made its appearance in the Muromachi Period. The design of the Tsuba is very simple with a round disk design and cut out work. The word Tosho means sword smith, however, this does not necessarily mean that the tsuba was created by a smith. It is more a reference to the actual style of the Tsuba.

This Tsuba is hand made of oxidized copper in the old tradition. The Sukashi is a butterfly with a standard sized Nakago-ana out in the middle. The Tsuba is a Maru Gata style.

The Tsuba comes in a wooden collectors box with a red velvet lining.
