Despite the leather combat cover on the saya, the koshirae are not military. The saya has a horn kurikata, the fuchi-kashira are civilian Showa examples, and the tsuba is an Edo period sukashi design. This was probably the sword of a civilian in military employ.


The swordsmith signature Sukesada was used by a considerable number of smiths spanning the later part of the Muromachi period (1392-1573) through the first third of the Edo period (1600-1867). This sword is probably Sue Bizen Sukesada dating from the later Muromachi period. The name Sukesada was used by more than forty smiths during this period. Some produced superior workmanship, mostly for special orders, and of these Yososaemonjo Sukesada, followed by Hikobeijo and Genbeinojo Sukesada are considered to be the most skilled.

Given the period during which it was made, the sugata could be described in a number of ways, such as uchigatana, chisa-gatana, ko-tachi or even katte-mono. Ko-tachi is probably the best description. During this period relatively short uchigatana made for single handed use, were of similar length and were fashionable at the time. This slender, graceful sword is light in the hand; single-handed use would be easy.
