This sword belongs to Jo saku ranking.

Special feature : The signature is mentioned as Norinaga but not the first generation. We have no idea this signature is done by more later generation, or could be the swordsmith with same name from other district like Bizen, Shikkake, Kaga or Yamato province.
I feel this signature is Norinaga from Kaga province but this is my personal opinion.
The signature looks genuine but as the blade is consignment sale item, we couldn’t guarantee NBTHK Hozon paper.
The blade is having active temper line and nice Jigane with clear Utsuri.
Koshirae : Japanese Imperial Navy sword mounting with vintage Tsuba.
Probably someone’s father presented family treasure for his son going to the front during WW2.
Aoi Art estimation paper : whole Oshigata.
