** 14C vs AEB-L These steels are nearly identical. If anyone can tell the difference between these two steels based on performance, it has less to do with the difference in chemistry and more to do with the different HT protocols being implemented, which would be true if you compared 13C26/AEB-L against itself with two different HT protocols - one to maximize hardness, the other to maximize corrosion resistance. 14C28N swaps out some carbon for nitrogen and adds more chromium to get a tiny bit more 'stainless'.
