Question about my Xikar. I have a Xi2 cutter that is about a month old that I got as a gift. The problem that I have with this cutter is it is not very smooth at all on the cut. One side seems to hang up about half way and the other has a slight studder. My question is this, is there anything I can do to make the cut a little smoother? I also saw you mention something about an upgrade in another thread, how exactly does that work?
