I noticed a week ago that the barrel on my Vniti epee does not seem to fit properly. It is not just a matter of tightening it, either. Even when tightened, it "wobbles" slightly back-and-forth. The epee still works, and this wobble is not causing any problems yet, but I am afraid that it may lead to a bigger problem down the road. My biggest fear is permanent damage/break of the blade. What should I do? I am thinking that it may just be a poorly made barrel, with bad threads. If it is not the barrel, should I try to re-thread the blade? What size die would I use for the end of an epee blade? Where can I get one? Thanks in advance.
