CPM-154 Hardness

I'm working on a couple hunters in cpm154 for my nephews for graduation. I have never used the steel and trying to decide on hardness. I will be sending out for heat treat. Any recommendations? Is appreciated.

yes. an engineer for crucible told me they suggest trying 63RC as it would hold up but I never did get around to that. I do feel, but never measured in any sense, that 61rc holds and edge quite a bit longer than the over rated 59RC.
Great info thanks Tracy.
I would ask Peters if they can do a low temperature temper and cryo treatment for you. I am told they will do it for 3V. If they target 61RC you'll be very close to maximum toughness for CPM154 and have very good edge retention.
