I agree with sharper is better. I was able to pull 3 shaves from a feather. I didnt have very enjoyable shaves with Gillette 7 O'clock Russian Greens, 7 O'clock Indian Blacks or Voskhod. Feather was the only blade I cared for that I have tried so far. Not sure which I should try next. The thing I don't like is this is my only razor that is particular with blade choice. All of the blades I tried work great in my other razors.
A Perma-Sharp gave me the best results yet. It is second to Festher in sharpness and for me, it is much smoother. So far, it's the best I've tried. Given the short-life problem I've been having, only time will tell if this is the blade I'll be using regularly.
