I have an '11 and it was a little stiff when I first got it. You can remove the pivot screw, add little blue loc-tite and adjust it to where you want it. You can also take it apart and adjust the detent to your liking (looser or stiffer). I have done this with all my EKIs and they all open smooth as silk with a flick of the wrist. If you don't want to do that, it will loosen up over time. Also, the weight of the blade itself helps when flicking it open. New, the '11 opened easier than the others, simply because of its size and the weight of the blade. Take it apart, clean it, put it back together and use the hell out of it. That's what it's made for.
