It seems like many feather fans have fairly course beards and don't have sensitive skin. As a pale, sensitive skinned daily shaver, I find I get the best shaves from careful regenerative pre/post routines and a forgiving blade.
I don't know if I have a course beard. But the first time I shaved with a Feather blade, it was amazing to feel how easily it cut through the stubble, as if it was hardly cutting at all. A fresh Feather blade redefined smoothness for me!
