Hey guys, I just got a new DE Razor, it's a butterfly razor made by Ambroley. The question I have is how tight should you tighten the blade into the razor. Because if I tighten the blade really tight, the blade bends a little bit in the middle. It shaves fine like that, but I was just wondering if it's better to have a straight than a curved blade for shaving. Has anybody ran into this problem, I know your supposed to make sure it's tight so the butterfly doors don't open while your shaving, but how tight is to tight?
