I just about sold my PM2 after getting it and having it open like there was grit in the pivot. I think it was one of those 'this knife is so great, get it, you won't be disappointed' situations where you get the knife and you're totally disappointed. Add to the fact that I picked up a cheap Zancudo for $29 the same week that is a great knife.
I took apart the PM2 and cleaned out the pivot and bushings. Put it back together and no change. Still gritty.
I stripped it down again determined to find what the issue was. I inspected everything in the pivot and didn't see anything that jumped out at me. I then looked at the detent ball and ran my finger over it. Grit and drag. Now, I couldn't get a close enough look to see if the ball rotates in a socket or if it acts as a slide. So, I don't know if it wasn't rotating, or if it just had some grit stuck to it. Either way, I worked my fingernail over it like you would on a stuck ball point pen. I felt something give, and it was suddenly smooth. Put it all back together and bam! I suddenly start to understand why people like the knife so much.
So I'm going to carry it for a week and make a choice after that. It really is super smooth now and feels like what I expected from a $100.
