I also wanted to get away from CPM-154. I got some RWL34 and just in process of using it now. Only a couple folder blades and 1 larger knife started. Grinds and drills real nice. About all I can say for now but from what others tell me its a great steel.
While my preference is actually 14C28N but since it's so hard to get I use AEB-L which is very similar. I have long felt AEB-L offered the best "bang for buck" of any of the steels, and the article by Larrin confirmed this: https://knifesteelnerds.com/2019/03/04/all-about-aeb-l/
AEB-L is a great steel. I’ve found it works well for smallish knives up to 4-5” blade length. It holds a very nice edge and is easily sharpened to more than serviceable levels. I can’t say definitively that cryo makes a huge difference but I do it anyway.
