Dear members,
I came across this tanto made by Hisahiro, as mei indicates: resident of Akikuni, Hiroshima.
Made Keio2, 5th month: May 1867.
Hisahiro seems to be from Hizen school.
I wonder if anyone has any reference about ranking and rarity as i can't find any other example under his name.
In meantime i heard he is descended from the 8th gen (hachidai) of the famous swordmaker Hizen Tadayoshi.
