Edge retention on carpet : cKc-X, O1, S30V, k390

Edge stability is useful in some aspects for sure, but don't discount wear resistance as useless either.

Yes, no different than corrosion resistance or toughness. Imagine if tomorrow toughness in steels was argued the same as low stress abrasion resistance. All of a sudden a knife steel was high performance only if and simply because it had a very high impact toughness. Isn't that a really silly viewpoint, of what use is the extreme impact toughness of a 4340 blade on a fillet knife - would it not be better to have a 12C27 blade which has much higher corrosion resistance, a much higher maximum hardness, more wear resistance and while it is no wear near as tough as 4340 it is tough enough for a fillet blade?

Intuitively your arguments make a lot of sense.

To clarify, there is still a fair amount of work to be done before I would even feel comfortable giving that argument even minor credit. At a minimum :

-a lower angle/more coarse finish (10 dps/x-coarse DMT)
-push cutting sharpness comparisons

I am also going to see if I can find a SEM locally because if I could see the apex at the sub-micron detail it would make figuring this out a LOT easier.

Keep it up and maybe someday we will get a FFG zero grind L6 delica. (If I am understanding all this right)

Yeah, and optimized HT for strength.

Here is what happens if you scale the edge retention by the amount of grinding necessary to apex the blade :

hmmm this is quite interesting but not to know about its factors.
