七郷吉信 is the name. I couldn't find anyone who could translate it properly or knew anything about the maker. 作 means "made by."

On srp someone translated it and on german knifeboard someone does aswell. Both wrote something bout yoshinobu.

The srp member wrote:
The maker is Yoshinobu Nanagou or Shichigou or Nanasato the kanji after his name even though spelled one way can be spoken the three ways I have written depending on where he lived in the country so it could also mean the town he made the blade in

So if someone know the maker contact me
