I bought a dragonfly2 (FRN VG-10) about two weeks ago. My pocket clip started to come loose so I decided to get my T-8's out and tighten it back up. The screws will not tighten completely. It seems like they are stripped. Am I doing something wrong or are they just stripped? I don't want to have to pay 20 dollars for two new screws from spyderco.
