Well said Mntn Man62. My thoughts are the same on this topic. There’s great economy in using a DE razor and the shaves using one are superior than with using a cartridge razor.First of all, cartridge blades don't last as long as they say they do. When I shaved with a Mach 3 I would use a cart for about a month. But that was long beyond it's useful life because my shaves would start to go downhill long before that. But they are so expensive that you want to squeeze every drop of value you can out of them. I probably suffered at least a full week of shaves with lots of irritation because of this. With double edge blades, they are literally anywhere from 5 to 50 cents a blade (when bought in bulk), depending upon which blade you are using. So, if you get 2 to 10 shaves out of it you are more than getting your money's worth. I have also found that I can get a much closer shave with a double edge so that I don't have to shave every day and can go every other day if I like.
