Not so sure about PD-1 as far as real use goes, I do have a CPM Cru-Wear Military, but haven't done anything with it yet.
CPM S110V, I have a lot of experience with that steel and I use it everyday in kitchen in a custom fixed blade. It will take a very fine edge as it is pretty fine grained and clean, but with the wear resistance it will take most people more time to sharpen than steels like S30V. I find ceramic works excellent touching up S110V back to a screaming sharp edge in seconds, I keep my knives I use in the kitchen very sharp, usually sharp enough to drop through (Cut) a paper towel length wise without tearing, and that's not a polished edge either. Try it if you don't think that's sharp...... And that's off a Spyderco Professional Medium File (Ceramic), same as the Medium Sharpmaker rod for the most part.
