I tried a small test run with my DE shaver tonight. I got a little razor burn, but the shave was a little bit worse then when I used my cartridge razor BUT it was just a small test run, and my lather was not very thick. My question is Should I replace my razor blade if I drop my razor on the floor. I did this after I shaved tonight. I would think the safety bars would protect the razor, but I really don't know. I am using a Canadian Gillette Fat Handle Tech DE Safety Razor. Thanks!!
