I'm sure lots of people on the forum either have Watanabes now or have owned one in the past. My own thoughts are that they're great knives, even if they aren't a current fad. Traditional clad construction, with pretty reactive (at first cladding), fairly robust, blade heavy, with a generous curve that suits them to either rocking of push cutting. A lot of those qualities aren't celebrated right now, but they are well made and the blades are beautifully finished. Probably worth getting the octagon handle option in my opinion.
I'm sure if you wanted to learn more and started a topic many others would offer other thoughts.
