I am wondering how many of you use blue loctite on the pivot screw? It seems like there is a sweet spot where the blade is centered, flies open like a rocket and can still drop freely when lockbar tension is released. I notice that this only lasts about a dozen flips and then it is not centered (not rubbing either but...OCD) and isn't quite as tight when locked up. So just curious...anybody else run into this and are using blue loctite?
