Yep. That's what's so cool about this internet ,, for 40+ years I shaved with a Gillette fat boy and wilkinson blades!! didn't know any better !but doing it that long I got great shaves , then a few years ago along came this information on the web! I started trying different blades ,, now I know what a truly great DE shave is. Although my blade of choice is the Feather, and I change every shave just because I can and fresh blades perform exactly the same every time with my razor set on the 7 setting. Tc
