Geez, You win. You have all 4 of the ones I have and 3 or 4 extra. It's the only pocket knife I have used where the action makes me feel like I won't ever cut myself during the opening and the closing.

PM2 is my constant companion, except when I carry the Salt 1 running or swimming.
Also have and enjoy couple Manix 2, a Domino, and Sage 1.
Sal and Eric make a heck of a folder, and Ethan does not. I find them quite complementary.
