I bought a 2014 Case Tony Bose Lockback Whittler , it's a great knife in every way except it grinds when opening and closing . I figure it's the tang grinding against the spring , but due to the tight tolerances this beauty is made in it could be anything . I flushed it a couple times with gun oil and have opened and closed it about 200 + times . Has anyone had this problem and if so what did you do . Also any ideas would be welcome . I'd rather fix it myself if I can , but will send it back to Case as a last resort . Thanks .
