Hi.
Very quick post for this knife I have come across. Please help me out here to identify.
Kanji reads 幸之祐 (Konosuke).
Do you think it is an original Konosuke?
Konosuke has 3 honyaki makers. Shiraki for blue steel, Ashi for white and Genkai for single bevels. That definitely looks like a Shiraki for sure but can't be sure till I see the kanji up close. You definitely hit the jackpot if that is indeed legit.
