I don’t disagree with any of it. Ofcourse different heat treats make a difference. Different geometries also make a huge difference. You can’t compare steels like that. You can compare knives and say that some low alloy knife cuts better and longer than some high alloy knife. You just can’t generalize knife performance to all the knives made out of the same steel amd then conclude that one steel is ”better” than the other. I hope that by now with all the effort that was made by people in the community it is clear that in order to compare steels themselves in the least all the knives have to be the same in everything else.I agree apart from toughness Magnacut will outperform AEB-L in everyway, but my point was the different heat treatment by makers could result in vastly different experience. For example one maker's Aogami super last longer than other's VG10 at 60 HRC, while in theory it shouldn't be. I'm comparing steels supposedly more close to each other, so high alloy is not always better than low alloy in some experience. Of course if we count in steel like Magnacut, M390 or Hap40 they are going to be significantly long lasting than any low alloy, but not all high alloy is going to behave that way.
