Since I am having a similar problem with a Joseph Allen and Sons and an Electric Co razor and maybe another one. I hone on Arkansas Soft, black and translucent. I can shave arm hair, but when it comes to the face the hair there is entirely different than soft arm hair. It feels sharp to the finger and glides over the thumbnail without a hiccup. The mention of bevels coming together makes absolute sense. Now my issue is how to get the bevel. I am rather new here and just cannot find the information I need and wish there were an ask and answer thread. I would start a thread on this, but have no Idea how to accomplish this. Any help you can provide on how to get the bevel, what to look for.
In using a marker, do you run it over the edge, which is what I am assuming. Next, if I do this, what happens if on one side the marker disappears after a few laps but there are marker scores on the otherside.
