Time period: about 1400
This extraordinary sukashi iron plate tsuba is of mokko form with inome corners, not seen on any other sukashi tsuba recorded to this date. The top and bottom three-quarter flower forms are the karabana, or Chinese flower, and in this form it was used as a mon by the Yoshida family, a branch of the Urabe family, who were, under the Ashikaga Daimyo, very influential in all things pertaining to Shintoism. The side mon are the matsukawabishi mon used by the Ashikaga family. This combination of these two mon indicates that this tsuba was worn by a very high ranking official in the Ashikaga shogunal court in the early Muromachi period. All aspects of this tsuba are unique from its mokko form to the inome corners which are to be seen on tachi tsuba, of soft metal plate, during the early Muromachi period. In addition, the rim is of great interest, for it is partly carved with a rope design, later to be seen on the tsuba of the Takahashi school, and has many very fine iron bones as well. The place of origin, where this tsuba was made, is almost pure conjecture, but with the symmetrical design, the mon subjects and the quality of the work, we can say that the Kyoto area would be the best guess. This is the rarest, earliest, and finest sukashi tsuba so far recorded.
