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.
Old fashion polishing shows good Niku-oki and calm texture of jitetsu.
On close appreciation will keep you amused every time
but delicate beauty as it is tends to easily escape our notice.
Re-polishing with modernistic sense will make
the blade quite like a Shizu school Katana.
