Oh yeah I can't say I am sold on a blade needed to be cryo treated. As for the Rockwell Hardness I think in my opinion 65 in 0-1 tool steel is to much. 59-61 would be fine.
At that price you may want to contact MichiganRoadKill on here. He and I have been working on a knife design I think might fit your needs well. Ask him about the MCH blade.
