Feather Pro's--even straights I've sent out to be honed by well known people on here haven't come even close. I have about a 1 inch scar from a Feather Pro--the scary thing is when I cut myself, I thought I'd closely adverted disaster because I didn't even fell the cut. A couple of minutes later it started to bleed and that's when I realized how clean the cut was. I love shaving with the Feather AC, but I always respect it.
