When you get this knife apart you will find that the tail pc. is actually carbon fiber or some kind of hard rubber. Those 2 pins work together to keep the tension bar in place. Over time the synthetic material develops slop and the tension bar comes out. I had a small pc. of n/s and used the old tail pc as template and got this back together. Doubtful you can reuse the original tail pc. But maybe Kaleb can work his magic.
