Looking at the pictures , it appears that the trimmer cuts the case mouth almost to a point. Or are my eyes bad? Pre mature split necks ? Just asking , not downing it. I am considering one , but to me the other brand seems like a more precise tool due to the fact that you can adjust the chamfer / debur. I actually had one but had a problem with cs so I sent it back. Wish I would have kept it ( The things we do when were pissed ). I just would like to use one first , but that is not possible.
