I know this thread is relatively old, but I'd like to add something. If 1084 can make good razor edges, 80CrV2 certainly can as well and it's even easier to HT than 1084. Can be austenized from 1500°f to 1575°f. The vanadium also helps to keep the grain size in check. I use almost exclusively this steel along with W2(I use for hamons) for knives.
