Mixed feelings about undercuts. Have saved a few eyepieces from the concrete though.
Simple solution on the TMB Monos and perhaps others. Just unscrew the barrel and turn it around. That puts the undercut below the compression ring or set screw. The threads are the same on both sides but the undercut is not in the middle.
