With out getting into a whole fit and finish debate, I just got a new 15 and am curious how tight the opening and closing should be for break in. Currently the pivot screw keeps backing out after a bit of opening and closing, causing the blade to loose its center when closed. I got some lock tite and want to have the blade stiff enough, so that with break in, it'll be where is should properly be. Hope this makes sense, havent slept in 36 hours lol.
