Bob i looked Kanehide up. i could not find any of his swords for sale to get a price refference.
i think i was right about the sword belonging to a high ranking officer from what i read.
HE WAS A MASTER SWORD MAKER PRIOR TO THE WAR AND WAS INVITED TO JOIN THE ARMY BLADE DEPARTMENT IN 1941 (SHOWA 16). HE PRODUCED HIGH QUALITY CUSTOM BLADES FOR HIGH RANKING OFFICERS.
so i have a feeling its better than run of the mill.
