Hmm, why not H1 steel? Looking at the price of H1 knives VS S30V, it seems somewhat cheaper.
I also always thought that H1 would make for a better kitchen knife steel as a gift option for non-knife people. It seems the general user forgets basic things like cutting on a soft cutting board, wiping the knife dry, and keeping them out of the dish washer.
If edge rolling occurs much more frequently than chipping, it'll be easier to fix up. Also it's a true stainless knife which is important whenever you walk into a friend's kitchen and find all their rusted kitchen knives.
The grinding issue could be a problem given that it's hard to use a kitchen knife with a hollow grind, but I figure you could sidestep the issue by making the entire blade thinner(which hopefully also means considerably less grinding). Of course, one Mora chef knife I bought had the same width from spine to edge and was fairly thin, I figure that blade design could work well with the work hardening issues of the steel.
