I shaved with every new razor ever invented, starting years ago with a Gillette double-edged razor. A couple of years ago I was at Sam's Club looking to buy some replacement carts for my super-duper high tech razor, but the price was what we used to pay for a small car. I thought that there must be a better way.
So, I came home, got online and bought an old-fashioned double edge razor (actually two of them). They're both Merkur slants, a long handled one for home and a short handled one for traveling. Along with the razors I bought 100 Feather blades. The razors were reasonable and the blades were ten bucks. Blades of any brand are ridiculously cheap.
I've also started making lather the old fashioned way, using a brush and shaving soap, 1000 times better than anything out of a can.
All you need is a good lather and ONE sharp blade. I'll never go back to multiple disposable blades no matter what. I get baby-butt smooth shaves nearly every time with no nicks or razor burns. Try it.
