Thin and sharp
Gillette silver blue is the sharpest among all available. Some of the blades are not very flat but that does not affect the results. I would encourage the make in Russia to continue Silver Blue forever. Restarting "Super Silver" would also be great.
I've used several different brands of razors from West Coast Shaving. Gillette has been my winner. Both Silver Blue and 7 Hour are the best with which I've shaved.
My blade of choice.. 4/5 sharpness
This is my main blade. There's not a razor I own that doesn't like this blade. I'm so happy they're still available in the states as there seems to be perennial chatter of them going the way of the dinosaur. Really top notch.. They're a 4 out of 5 in terms of sharpness: Not as sharp as feathers or kais.. I find polsilvers to be maybe slightly sharper as well, but they are certainly sharp enough for me. Far better than the Gillette sharpedge blades which might have replaced them some years ago. The best thing about these blades is easily their edge retention.. I've gotten 15 shaves in a pinch from one of these guys. That's, for me at least, better than kai, feather, personna, really anything else.
New product with old trusted name
