K888 vs CPM 1V: High toughness at high hardness?

Compared to those we discussed, it seems to have much more noticeable edge retention. Not a whole lot less than 3v, but way higher toughness. For my uses it’s a much better balanced steel for the type of knives I make. The only thing putting me off is the high price. I think you know what my choice in blade steel is, as far as price to performance! But if cost wasn’t a concern, I’d probably stick with 1v. I am going to make a boning knife in this steel before my hunt. My current thin stock boning knife is in magnucut at 62 rc. I’ll try this steel at around that hardness. And see what I think.
 
What have those who have run 1V been using for temper and Austenizing temps?

Ive run Z-Tuff with Larrins recommended 1925ish and 400 for temper. I got 61HRC via PHT and it performed awesome.

Has anyone messed with low temper on 1V, if so what were the results?
Im going to be working on a 1V xhopper soon and im thinking of shooting for 61HRC like i did on the Z-Tuff. Curious if I can run the same heat treat cycle as Z-Tuff and get similar results.

My HT protocol 2050F/30/cryo 64rc 300F, 61rc 400F

Hard wood(blue gum) chop test (63rc,15dps, ~0.015 bte : 1V, 3V, CD1, Ztuff, Magnacut) = excellent(no edge damage) , preferred magnacut then 3V for corrosion/oxidation resistance.

Notched/cvn (2.5x10mm) impact test 5 steels: 63rc: about same ft/lbf +-error margin from each other. 61rc: 2.5x of 63rc, except magnacut is 1.2x of 63rc # *note: my internal #s, thus fwiw post.

Thank you. I'll likely use that heat treat. Just need to choose final hardness.
Looks like impressive results!
