This is a katana by Yoshisuke from Suruga province. He was active during the late Muromachi period, around the Daiei era (1521-1528). There are several smiths with the same name, but the most common one is the Yoshisuke from the Tenbun era, known for his large two-character signature where the "義" character resembles a "手".

The Shimada school (島田) took its name from its base in Suruga Province, where it worked from the mid-Muromachi period along the Tōkaidō between the Mino hearths and the late Sōshū smiths of neighboring Sagami. The published sources place its founding generation in the Kōshō (or Kyōshō) era and trace its principal names without interruption down into the shintō period, with the same names continuing as late as the shinshintō era.
