Those blade are suppose to be the new version of the Black Beauty, but they are not black and they don't need a special caring whit alcohol after each use. Well first, when i tried those blade my expectation were quite low. I had in mind, oh no, not another blade that pull and drag leaving you whit irritation, but , i was wrong. It turn out to be the best blade i tried so far, and i tried a couple, Feather, Lord, Derby, Bluebird, Merkur. In fact i like them more than Feather because they are less irritating and for the sharpness they are quite the same. I tried it in a Tech and had a very good shave, so i imagine that if use in a more aggressive razor, it works wonderful. I highly recommend that blade. Btw: Shoeboxshaveshop have it.
