Sukenari YXR7, Maboroshi, Yoshi SKD, and Kujira. I too agree that a thin and not-tall 210 feels more like using a petty as a gyuto, which is not necessarily a bad thing but is a different thing. Takamura Pro for instance. Surprisingly I didn’t like k-tip 210s as much as I thought I would. Had a Mazaki which I liked a lot but mine was really more of a 225 class and tall.
Some knives I don’t seem to care if they’re a little over or a little under the nominal size: notably the Maboroshi I had one a little under and one a little over 210mm and significantly prefer the one a little over. The Yoshi I think is just a great knife in general and when I get another to replace the one this doofus boosted (or at least borrowed and never returned) it’ll be probably a 240.
The Sukenari I got pretty recently and I’m not doing a ton of cooking these days, but the grind, profile, and steel are top flight. I believe it’s spot on 210x~50 and doesn’t ever feel undersized which I think is mostly a function of the geometry in the several dimensions.
The Kujira I’ve had for a while and I really have fallen in love with it: flat but not too flat, nice point on the drop tip, tall, tapered... it was also my first serious thinning project that I got sort of right. The stock grind was too fat and convex but now it is, if not perfect, certainly improved. However do note that this was a >$500 210 that took hours of work to make it into my favorite.
