This has always been an interesting topic to me, and I'm sure there are tons of threads dealing with steels...I'm not trying to start something here lol
Unless I'm understanding incorrectly, the only reason to use a stainless (in this application) is to slow down corrosion. Carbon steels seems to set the bar for hardness, and stainless is always trying to get there.
That being said, there are some superb fine grain stainless steels out there that the knife industry takes advantage of (Uddeholm, Crucible, etc). I'm just guessing that if the straight razor industry were huge, we see similar application of these to try and get the best of both worlds.
So congrats on the VG10 blade - it certainly has a good reputation.
