a while back I purchased an endura wave and really like everything about it except the pivot would come loose and develop side to side play after like 2 deployments. I want to love this knife but I can't if this is a typical problem. so since I'm considering giveing the endura another chance and I was wondering if any other endura owners had this problem or if this was just a factory mistake. All my other spydies lock up like a bank vault and I see it odd how I can 70+ on a knife with a bad pivot when I can go spend 40 on a good cold steel
