Let's see..
Dozier likes D2 so does Dave Winston, Charlie May ,Gene Ingram and a host of others.
I do not doubt D2 can rust under the right conditions but so can any stainless steel.
If stainless was TRULY rust proof it would be impossible to chemically etch a makers mark on it ,and yet we know that is not so..
The knives I have owned and built from D2 so far have been a real joy to own and use. None of them have caused me the rusting issues of carbon steel blades and the sharpening issues are really non issues with modern Diamond and ceramic hones.
D2 even works fine for Convexed edges. Yes, it takes a bit more work to get it stropped up but once you do, as you touch up the edge, they seem to get sharper over time as the tough carbides along that edge get more and more aligned..
It's a damn fine knife steel. A D2 Eskabar is a welcome addition to the world of Beckers.
