Also, maybe there's a lot of variance between Hiromotos? Maybe Hiromotos out of the box are thick? (I've even had wedging with other knives that were asymmetric, symmetric, sharp, dull, thick behind the edge, thin behind the edge. Your simplistic answer is pure speculation.)
Even you've said that Hiromotos need work and thinning to bring out their potential. The OP specifically said he doesn't want to sharpen a lot. You think the AS is going to have better retention than the CarboNext (for example)?
We know you love Hiromotos, but have you ever compared a Hiromoto side by side or owned any other knives that the OP is considering?
