So I just received a Para 3 lightweight, and the pivots seemed quite tight so I tightened them by a few millimeters. The blade was all of a sudden very very tight and would not drop shut or flick open. I then went to loosen the pivot screws but that did not help, so I went ahead and adjusted some of the body screws. It seems that whatever I do, whenever I get to the point of adjusting the pivot screws it becomes extremely rigid. In order for it to drop shut the pivot screws need to be poking out of the handle scales which is not good. Any ideas as to what this could be? Do I just have a weird model? I know the LW isn't as smooth as some larger heavier knives but this seems very odd to me.
