Is anybody else doing this? I use Feather blades in my Merkur HD and, for a while, was changing the blade after 3 shaves. Towards the end of that cycle my shaves were just so so. Then I thought why not just use a new blade with every shave? The blades are cheap enough for my wallet. Significantly less then cartridge razors and I get a great shave every time. I figured that people who use a straight razor will strop it each time before their shave. So why not start with new blade in my DE razor before my own shave? Since I started switching out blades each time, my shaves have been consistently superb. Am I wrong or wasteful doing it this way?
