explanation: This blade is Sagami kuni Tsunahiro which was made at Late Muromachi period Tenbun era.
but at this moment, NBTHK judged Suishinshi Masatsgu shinshinto blade.
Probably NBTHK checked the Jigane carefully and judged not so old Jigane.
I think from the shape, the sword looks rather old sword.
Anyway I accect the sword as NBTHK judged Kantei.
