Help in identifying japanese chisels

[Carlo Petrilli]

Any help with identifying the maker of these chisels would be greatly appreciated:

If it will help I will try taking a better photo. Thanks for any information you can provide.

Carlo, some of the characters in your photos are a bit indistinct, but this board has some folks who are quite familiar with Japanese toolmakers and they might be able to make out enough detail to help you. You might also consider posting your question, with perhaps upgraded pictures, on japanesewoodworking.com.

I wonder if there's an online (or other) source for identification of Japanese toolmakers.
