I use this divider for woodworking. I prefer this type where the adjustment pin and internal threads are in the arms rather than on the outer rod. Because of this, the arms are fairly thick, well aligned when fully folded, and the adjuster is smooth. It is important for my work that they keep this attitude very well. It looks like it could be a quick tweak to make big changes, but I haven't worked it out though I don't care.
