Ken,
Certainly I'd be willing to share with you my displeasure with CPM440V.
Ok, first let me say that CPM440V is not a bad steel at all, in fact, it's some pretty hard stuff. However, CPM440V, because of it's high carbon content (2.15%), is subject to strong cases of carbide variance very shortly after sharpening. What does this mean? It means that you may spend an hour on your 204 getting your native to shave, and after just a little bit of pretty light use, you will discover that... while it still slices like a demon, it will no longer shave.
The carbide variances cause this, generating more of an uneven "biting" edge, which... again is great for slicing... but I do mostly push-cuts with my knives and this disappoints me, as this steel doesn't lend well to that use.
That, and CPM440V is a true bear to sharpen.
To be honest I've never tried S30V, but I've heard good things and have an open mind.
Also, for whatever it's worth, just to show that I'm a bit unusual in my steel preferences, of all the steels I've tried so far (which, it should be mentioned don't include S30V or BG42), my favorite is 440C
Anywho, hope this cleared your curiousity up some. (If you would like me to explain Carbide Variance in greater detail feel free to ask, but as my arm's getting tired, I'd rather not type a whole big explanation and discover you're already well-farmiliar with it )
