So I have been slowly working through my sample pack of blades getting mediocre shave after shave. Then I decided to give the feather blade ago and what a difference it made, such a good shave a DFS with minimal effort and a bbs with a few little touch ups. Now I am on an Astra SP and it is no where close to what I could achieve with the feather. So I guess my question is....... has anyone else experienced this as I found it hard to believe that a blade could make such a difference
