I received a CRK 25 for Xmas and recently started to edc it. When I first got it I found it difficult to open and that caused a delay in my rotation of knives. Just when I thought I broke it in the situation started to get worse. The blade tang is actually rubbing against the pivot stop pin! I thought a drop of lube may help but now it's like the blade has become frozen and barely rotates without force. Mind you that I own around 15 sebs! I'm going to try cleaning it first to see what happens. Any suggestions?
