So my Paramilitary 2 came in the mail today, and the blade is really sticky and hard to move. It's not a sticky lock, because it's just as difficult even with the lock fully depressed. I tried adjusting the pivot screws, but only one of them moves, the other is completely stuck (which is probably the reason why I'm having these problems). Any advice for either how to get the other screw moving, or how to loosen up the blade? Thanks!
