I have had my DE longer than I have been shaving. I found it when I was a kid. I have been using it for about 45 years. I have never had to buy a razor, just blades. I have had good luck with several different name brand blades but got a very short usable life out of off brands. I have a beard, but still have to shave my neck and cheeks.
I inherited an old bone handle straight razor, but don't know how to sharpen it properly, so I have never used it. I read Will's sharpening method, but think at this late date I will stick with the DE.
