Previous answer is
　 Mumei (Yamato Shizu)　

Special feature:Shizu-Saburo-Kaneuji was a swordsmith of Tegai School, thought as a pupil of Masamune in Soshu province,
later moved to Mino province from Nara in Yamato province and prospered with his school.
Yamato-Shizu is the general term for the School before moving. In the narrow sense, it means only Kaneuji.
The workmanship of this katana resembles to Kaneuji or Masamune.
It is rather close to Shizu style though the general workmanship
of Yamato-shizu has a tendency toward Yamato style.
