We've found that humidity makes a big difference,
I'm going to test that theory, Sal. I'm out east in Thornton and as you know we've had dry, windy weather lately. Tomorrow we're having T-storms with rain. I'm going to take the Para 3's out of the relatively dry safe and see if something changes in the next couple of days.

I think it likely that after initial use, as the lube was spread out, that gunk from manufacturing got into the pivot area and started dragging the blade. Perhaps a good cleaning? Or, it could be that the pivot has no locktite and it worked itself tight over time and use (I have had this happen with BM's, some loose, some tighter).
The thing was Dan they were tuned up just fine prior to leaving for CA. When I did re-tune them the pivot screws were still snug enough to stay put. I know what you mean about the BM's. I've got some I've tried to adjust and when you get them where you like the action the screw is just on the hairy edge of breaking free.

Ok let's be serious and break this down. Do you take your knives apart? If so, do you also use a thread locker when you put them back together? On my Caribbeans I have polished the blade tangs and if I don't reassemble them with the washers on the right side and even flipped in the right direction it will effect pivot action, but this is felt immediately after I put the knife back together and not 2 days later.
Nope, I've never taken these apart. I have noticed that over a long period of time here at home the action may need a tweak, but this was pretty sudden.
You need to eliminate some variables for us.
Which force/part of travel are you noticing this for? Opening? Free-swinging with no lock pressure? Travel with lock pressing against tang?
Which lock type?
Did you notice a change in blade play?
Yes, instead of free-swinging when closing these would come to a stop with the same amount of body english applied, and I had to apply a little more force to flick the blades open. So, free swinging and with lock pressure. No additional wobble in the blade, though.
