Gentlemen,
Feather blades are exceptional in overall sharpness and quality, although not suited for every face or every safety razor. Many shavers note that the second shave on the Feather is smoother and more comfortable than the first. It seems to be for me, too. Either way, two shaves and out for me per blade. I do the same with my other preferred blades: Super Iridium (I still have some left), Polsilver Iridium, Astra and Gillette 7 O'Clock Sharp Edge "yellows." All good stuff.
