Yeah, great pick-up, Son! I was after that one for myself, but you deserve way more than I do!
I can't really think of too many profiles that have made me go, "This thing isn't right", as I seem to just change up my technique a little bit to fix the "issue". However, I have a couple all-time favourites, and they are Robin's gyuto that Pierre Rodrigue made, with the inspiration of a Carter. The proto of his that I...ummm...used...is very similar and it just has that ability to chop, walk and do fine tip work that many profiles can't combine too well.
I'm currently using the Mike Davis passaround (and sleeping with it under my pillow, but that's none of your business) and its profile reminds me of the Misono gyuto profile, with no true flats, but such a gradual curve that the heel area still feels flat, without any clunking. The tip is microscopically less adept at fine work, but overall, it's damn near perfect in the profile department.
My order goes:
Misono gyuto
Rodrigue/Carter and Davis tied for 1.5th place (
