Gillette SharpEdge are my new favourite blades, and I have decided that they are the only blades I will be using from now on. In regard to sharpness, they remind me of Feather blades, but I much prefer them over Feather for two reasons: they're significantly less expensive, and they are much smoother and don't cause any irritation at all (Feather blades always felt abrasive and scratchy to me). I have an unfortunate combination of sensitive baby skin and coarse pine-needle hair, but these blades are the perfect solution to that quandary because they will effortlessly mow through the most coarse hair and cause no irritation whatsoever. Quality control for this line seems to be excellent as well; I have yet to encounter a defective blade. I can usually get about five or six shaves out of a blade before I have to change it, so I would consider that a pretty good value in terms of longevity. Everybody perceives blades differently, so there will be some people who don't feel the same way I do about them, but it's definitely worth trying a pack if you're seeking a smooth, sharp blade that's suitable for coarse hair.

One of my “go to” blades that I use in my DE89 safety razor is the 7 o’clock green (RUS). I read a lot about ppl preferring the yellow, so I thought I’d give it a go. This blade is not for me. It seemed sharper and more aggressive than the green, even though they are rated the same. In a 4- pass BBS shave, it left me with several nicks and a very irritated neck, post-shave. This probably has more to do with characteristics of the DE89 design than just the blade itself. While not as aggressive and sharp as a Feather Hi-Stainless, it was still too much for me to warrant a future purchase.

Very good

My go to! I have a cabinet full of Astra because every review said they're the best. But the 7 0' Clock in my opinion is smoother, closer and far more enjoyable.
