It was just off.Interesting you mention about the dial! I wonder how smooth are they supposed to be anyways. Mine does seem to have a little resistance. Nothing crazy though.. like it isn't "hard to turn".. there's just a little resistance. I think it has gotten a tiny bit stiffer since I've been using it.. maybe a little dried soap scum inside or something. At the same time you wouldn't want it too loose either.. that the wheel could be accidentally turning while you're using it. I wonder if maybe the dial might benefit from a single drip of oil to the dial now and again to keep them running smoothly.
You should oil the razor from time to time.
Pretty sure Matt has a video on caring for the Rex and Konsul (and similar adjustables) on the Razor Emporium site.
