I can attest to the problem of the pivot screw working loose.
Mine does CONSTANTLY.
(GOTTA get to Walmart, outta LOCTITE!)
That's not as bothersome to me as the fact that mine came with the clip screws stripped out! They'd stay in there, but they weren't tight and I just KNEW that I was gonna lose a screw.
Having heard repeated stories about how long it takes to get service from Emerson, (not judgin, just SAYIN!) I decided to go with RED loctite on those screws. The red stuff is permanent unless you put 450 degrees on it, so they SHOULD stay in there.
(whether I want them to or NOT!)
I'll put blue on the pivot screw, but as was said above, when shelling out 150 bucks, I don't feel like I should have to deal with this kinda thing.
On the OTHER hand
MAN is that wave feature COOL!
The blade flies open so fast I usually have to show people two or three times before they begin to figure out how it opens itself.
GREAT knife, but QC could use a little improvement.

I cut it, and I cut it, and it's STILL too short!
