I have a Merkur Progress and I would like to know with the blade inserted and tightened down fully what number should represent zero? Should the "+" represent zero or "1''? Thanks Joe
No matter what mine sits on the gap between the "+" and #1. Practicing, I started off on the 1 and now have it set most usually at 2.5 where it delivers a great shave. My question qould be IF I sent the Progress up for the Mergress stainless adjustment knob would it be, or is the calibration, truer?
