Suketsugu of in is a name the published sources say was carried by three smiths, from the early to the end of the period, and the blades on this record belong chiefly to the late- Chu- Suketsugu of the Showa era. A signed no Higashi-no-sho Suketsugu and dated the sixth month of Showa 1 (1312), recorded in the Koyama , fixes his time, and the published sources write that "the Showa 1 date is the oldest among -made swords". Tradition makes him the son of Toshitsugu, and the name ran on to the end of .
His steel is the steel. Over an that stands a little and flows in places, with and large grain mixed here and there, the of the school appears with , and on one a rises in the . The published sources describe one of the Showa as one that "shows well the character of the school of this time", and another as one that "shows a typical form of the school of this period".

Of a long signed no -ju Suketsugu with a Showa date they write that cutting a large signature in the middle of the tang on the "follows the tradition handed down since ", and that the whole "leaves an air of antique elegance".
Two blades sit at the edges of the name. A signed no Seno-ju Gyobu no Jo, dated Bunpo 2 (1318) with the maker's age of seventy-one on the , shows that the Seno smiths kept their own identity beside the smiths; the published sources call it "precious for research" and find its manner "akin to the neighbouring Kagemitsu and others of the time". A broad, shortened with an extended they judge a work reaching into the that "shows the manner well".
His record holds seven designated works: one , five , and one prewar from the Maeda family, formerly of Maeda Toshinari. Dated, long-signed of the Showa era are few, and an example of this kind comes to market only rarely; when one does, its signature carries as much interest as its steel.
