The Bizen Sukesada line of sword-smiths descended from the Osafune school and are recorded as far back as the end of the Nambokucho period. During the late Muromachi period there was a great demand for mass-produced swords (kazu-uchimono) and the Sukesada workshop had a solid reputation for producing high-quality fighting swords. At this time more than 40 sword-smiths used the Bizen Sukesada name. Sukesada’s most active period was in the Genki and Tensho eras (1570-1591). 

The hamon of this katana’s upper half and bottom parts have relatively different styles, which was common at the time, but not in Sukesada blades. The presence of utsuri and the rich hamon suggest that this sword is far above the average quality of kazu-uchimono.
