Referring back to an old post.
Have you ever tried to shave with one of those single blade razors you get from hotel front desks? I normally shave with at least a double (maybe triple) blade. When I was in Ithaca, NY on a business trip, I forgot my shaving kit and had to ask the front desk for one of these suicide blades. Now I realize the purpose of the extra blades. I guess it spreads out the force across your entire face so you don't cut yourself as often or as severely. Maybe it's just a matter of practice, but DAMN! I'm not sure if I'm ready for 5 blades, but I'll stick with 2 or 3.
