Thanks, all. I remember trying some other screws with the same outcome. Weird, but I've been carrying for half a year, once or twice a week on average. The screws were fine then recently I felt the clip come looser, side to side action. Got the tools out and then they wouldn't seat properly. Spin spin spin. Don't have a loupe, great suggestion and thanks on the reverse screw hint also.
I'm going to look at them one more time today after work and then send them on back for warranty service. Good thing I have a few other knives. Will send in my ZDP Endura at the same time just for a sharpening, may as well. I have been using the Sharpmaker but want to see how both of those come back from sharpening vs my sharpening. I can't ever seem to get exactly what I want on S110v for sharpness after the 4 grits (diamond to ultra fine) then a green compound strop. My best work on the Sharpmaker is with 204p and m390.
My green C-Tek scales from Cuscadi should be here in days and I'll fit that to my NIB Rex 45 PM2, can't wait to see that come together. You know I'll post pics!
Aloha and mahalo, y'all!
