What works for others may not work for you.
Look at the knives that you have. The blade on a BM940 is quite different than on a PM2 - which one feels better in hand? Which blade profile works better for you? That is a start.
I find that the folders that I prefer all have a similar "belly" and blade height/length.
I've carried a Hogue 4 inch drop point EX01 every day since August 2015. It's blade was closest in profile to the Knife Research Rasul fixed blade that I carried every day for 14 months before that. This Hogue is an extension of my hand - it is hard to replace. The ergonomics of it check all of the boxes for me,
It is also priced low enough that I can break it, if needed. I have a spare ready. A Wilson Tactical Star-Light is on my radar, but, basically, the same knife as the G-Mascus model that I carry. Very light and very strong for its weight.
Look back at your favoUrite knives from the past....knives that saw a whole bunch of carry time....and find the design that worked best for you. If you choose to try something in a different style, I would suggest picking up something, lightly used, on the Exchange, before throwing down $400+ on something that may not "fit".
It's easy to get "Knife Poor" if you go in different directions, haphazardly.
Good Luck!
