Historical Background: Naoe Shizu
The attribution to Naoe Shizu refers to a group of smiths who moved from Shizu in Mino province to the Naoe district during the Nanbokucho period. They were followers of the famous smith Kaneuji, who was one of the “Ten Students” of the legendary Masamune.
Swords from this school are prized for combining the power of the Soshu tradition active temper lines and rich nie with the technical characteristics of the Mino tradition. Because this blade is o-suriage, the original signature was lost, but the quality and style allowed the NBTHK experts to firmly attribute it to this prestigious school.
