Bishuu Osafune Sukesada started from early Muromachi period
and been successful until Edo period.
At that time, demanding swords are increasingly high so mass
production system was introduced.

thickness with deep sori and longer kissaki nice looking shape.
The jignae is item had and mokumehada mixed nice Jigane and utsuri appear.

Even though the blade is called Kazuuchimono but the blade itself very nice Jigane
