This sword was made by the 6th generation Yoshisuke of the Shimada school (YOS 1678). Hawley however seems to have mixed up the generations, though he has also done this with other smiths. Hawley rates the 6th generation Yoshisuke at 15 points Toko Taikan rates the smith at 2.8 million yen, whilst Fujishiro (S 107) rates him as Jo saku.

The Shimada school, which was founded by Yoshisuke, thrived in Shimada of Suruga Province from the middle of the Muromachi Period and the smith name of Yoshisuke was succeeded to until the Edo Period.
