The length of this blade is more than 70 cm long and must have been easy for its owner to handle it back then. The blade comes with a beautiful set of Katana style Koshirae(decorative sword mountings). It would be nice to have a piece that was forged in the warring state period. This sword has a Hozon certificate issued by NBTHK.
