Pretty sure Suisin's single-bevelled Dreamcraft gyutos are the thinnest and would be surprized if Carter's gyutos were as thin as or thinner than Takeda's (not that they should be, either. A single attribute in isolation doesn't make a knife better or worse. I'm told that Watanabe's gyutos are thicker than Carter's and Takeda's, but I'm not told anyone has ever or would ever mind).
