Something about Kanji, particularly engraved kanji, makes me feel less conscious about the branding of the knife. A stamp that says NENOX! or the like just makes me think big company / Wustoff type knife. Now the knvies I have probably do come from the same type of company / facility that a stamp branded blade does, but just seeing kanji makes me think less about that. I'm weird.
Put all the Japanese writng you want on them but I think they should still have a brand name in English on the blade. I have stacks of Japanese knives that after 3 or 4 years I don't remember the maker of anymore. If I ever knew.
