As far as my reasoning for staying with a stainless steel, I just think the ease of caring for a stainless knife is good to have. After a day of hunting and maybe field dressing a few deer and just wiping the knife off with a paper towel or rinsing it quick with water, I'd hate for him to forget it in his pickup when he got home and then find out it had rusted the next time he goes to use it.
I'm with you when it comes to non-coated stainless steel. I got a BRKT Bravo I and I have some problems with corrosion. But that's why I mentioned the coating that protects the blade. I "insist" on considering carbon steels because there are so many good knives that are made out of "rusting" steel (for example ESEE!!!!!!!!!).
Another thing I'd like to point out is that after a day of extensive use you need to take care of your knife anyway - doesn't matter if it's made out of 1095 or 154CM. I'm talking about maintaining the sharpness using a strop for example.
But if you are really looking for a stainless knife in S30V maybe the Doug Ritter Mk3 fits your bill. I never had the chance to examine one but it looks great, Benchmade provides high quality and I heard some good reviews about the knife. But it's expensive (I believe it's about 170$).
From what I heard Entrek make some nice knives as well - ok they are made out of 440C but I guess they know how to heat treat that stuff right.
After searching knifecenter.com I guess you are better off with a custom knife maker
I hope you gonna find what you are looking for
