These are by far some of the sharpest blades I've tried. My favorites have been Bolzano Superinox and PolSilver, but I've found that Bolzano is not so forgiving, and PolSilver seems to dull top quickly.
I have the fortune of being self employed, so I don't have to shave daily if I don't want to. When these blades arrived (very quickly) I was sporting a three day growth. The 7 O'clock cut through it like butter. But I also didn't get any cuts or nicks as I experience with Bolzano. Plus, after four shaves so far, the blade seems just as sharp as it was the first time.
After reading so many reviews for all the blades here, I'm starting to realize that the most important factor in a blade's performance, is one's face. Some blades that others swear by, seem to rip the hair from my face rather than cut it, and others that people hate, work very well for me. I think hair thickness, skin thickness and consistency, make a huge difference, so it's best to try all the blades you can to find what works best for your face. I've yet to try many blades, but for me, Gillette 7 O'clock is now one of my favorites, and I'll try all the other Gillette blades.
