Hey all. I received a PM2 from my wife on Christmas and I love it. I thought everything about it was perfect. Then I flicked it open just now and I heard something rattle around on the floor and got lost forever. Now my knife opens from the lightest of touches while closed. I'm concerned because it will definately open in my pocket and slice myself. Is this normal? Is it possible the detent ball snapped off somehow and that is what I heard on the floor?
