..he's using the same term - if I am preventing edge failure due to deformation, I'm chasing strength. Correlated with hardness - correlated being the key term, there is still some unexplained bits as to why a lower carbon high hardness steel has lower yield strength than a higher carbon steel when it comes to a fine edge (I doubt if you started testing other strength that the higher carbon steel would fare much better - the higher cementite works against ductility).

So, yield strength, I guess with some consideration toward grain and some unexplainable bits by picture (the lower carbon steels always look great in pictures if they don't have much for alloying in them, and they all attain good hardness in a fast quench).
