I am currently working on a batch of blades I made out of CPM 154 at 61Rc with double cryo cycle. I have sharpened a couple and am really impressed with what I personally see. A couple of 'fire members will be able to give a report on how it performs in the field and relative to other steels.

I have used 52100, A2, 440C, 154 CM, CPM S30V and now CPM 154.
All have performed very well.
Its all about the geometry and the heat treat you know.
Just my observation.
