Tim,
RWL 34 from Erasteel is a functional replacement for CPM 154 - it's PM and has 0.2ish% V.
We've discussed BG 42 before. It's from Timkin-Latrobe and while not PM it is double vacuum melted which makes it super clean. Has 1.2ish% V. Absolutely one of my favorites - My old Sebbie in this steel is my number one EDC ever.
I love the U2 as shown above - another of my favorite production knives. My kid and wife EDC them. I call it a Gerber LST on steroids. The steel is PM, from a Japanese company, but I haven't worked with it yet...
