So I have not actually started using a straight razor yet, but have been researching a bit. I have a "Harrison Ford" scar on my chin about 1 1/2 inches long. I have no problems shaving over it with my Mach 3, but my guess is that the ol' straight razor is a different story. I really don't want to find out the hard way though. Is this something that is doable, or should I re-consider? Any feedback would be much appreciated.
