A couple of years ago I had a minor cardiac scare and the cardiologist immediately put me immediately on a blood thinner. A couple of weeks later, I was happily shaving with my safety razor with Feather blades and I nicked my self under the bottom lip. What should have been a five minute issue with a little bit of spit and pressure turned into almost 90 minutes of bleeding! Just wouldn't stop leaking. I purchased a Mach 3 and eureka, not only no more nicks, but a superb shave as well. Two passes and BBS all the time. I use a Simpson Commodore X2, Arko soap, Proraso Green soap, and currently also have in my rotation Speick cream. That said, what's the beef with the Mach 3 or any other cartridge razor? It can't be cost, because you guys seem to spend small fortunes on other parts of your shaving arsenal (razors, brushes, soaps, creams, etc). I'd appreciate any feedback. Thanks.
