I recently acquired a 20x jeweler's loupe with which to view the magnified edge of my razors and found that one of them has some pitting along the middle one inch or so of the bevel. Additionally, I can see what I will call micro chips along that portion of the edge where I've previously honed out some of the pits. This will account for the slight pulling I sometimes experience from that part of the edge.
I've learned to avoid most of the pulling by using the toe or heel of the edge to shave my chin. It doesn't seem to bother me elsewhere on my face.
So, what are my options? I would like to avoid removing a lot of metal, if possible. Is there some relatively simple way of killiing the rust without removing a lot of metal?
