I have not used Yoshikane SKD gyuto, but I have 165 Hakata. The knife has flat, wide bevel knife that is not the thinnest out there, but has great food release. The SKD steel is run hard - you should use micro-bevel to keep micro-chipping at bay if you plat to chop with the knife (I do with the Hakata). But you will get incredible edge holding.
Kochi - again I do not have the gyuto, but the 180 k-tip santoku. Incredibly thin behind the edge - I really mean that. The grind of the bevel is slightly concave - that is part of the reason why it can be so thin, but I expect that even once the concave grind will turn flat after a few years, it will still be freaking thin.
Munetoshi - I am thoroughly enjoying this knife. Noe too high, neither too thin bevel (again, slightly concave) - it goes through food surprisingly well, even through carrots if you give the cut a little of slicing motion. This knife is a workhorse. I holds edge better than I would have expected from white steel. It has also rather flat profile - not everyone likes that, I do.
Konosuke - I had 2 in hand recently (just for a few minutes, really), but I was impressed by the grind and profile.
