Sagami-no-kami Masatsune (1535~1619) is the 1st generation of Masatsune line. He moved to Owari province from Mino, so his blade is Mino tradition. His smith name in Mino was Kanetsune, then he was given the name Masatsune by the load of Owari "FUKUSHIMA Masanori". Once the smith retired and gave the name to his son (1607). Then the 2nd Masatsune died soon. So the 1st came back again, and he added the inscription "Nyudo" after the signature that means go into Buddhism.
