I just got my first Para 2 (Black with Digi-Camo). No blade play and blade is fairly centered between the scales. It is awesome except for the fact that it is very stiff. It opens smoothly, no grinding or stutters, but I can't seem to flick it open like in all the Para 2 YT videos! I have to thumb it all the way until it locks. Nor can I close it with gravity. I have to unlock it and close the blade with my other hand. Is it suppose to be this stiff?

Mine was the same. Loosen it and put a drop of oil on the pivot, then you can tighten it again and it should fly open everytime
edit: Loosening the pivot screw less than a 1/4 of a turn gives the looseness I was seeing in videos, but introduces blade play. So I re-tightened it.
