I have plain edged Jot with some vertical blade play. When I push the liner lock "more open", ie, move the lock manually past mid line, it reduces or kills the blade play. I've contacted Spyderco, and they suggested I return it to have it looked at. I was wondering if anyone has had similar problems (specifically with a Jot, but a liner lock with pinned mircata scales aswell) that they had corrected by syderco? I'm very interested in having the problem corrected and the blade reissued to active duty, but I am concerned about possible costs. Any ideas on what max fee would be to recondition this knife? I know I'm abit muddy with my description, so if there are specific questions you have that would make your answers more clear, let me know and I'll do my best. Thanks for any and all help, E.
