Cheers... yes thats the one.... honyaki with ebony handle.
I have a solid super blue knife (folder from Spyderco, not a kitchen knife) and I used vinegar to force patina on it. It turned deep grey. It looks good
I'll give the top one a go tomorrow
If you live in Europe I would suggest a Chosera 800 as a one and only.
Enjoy the mizuno then . (Do you mean the Mizuno Tanrenjyo? That's wa handles al over.)
