These are very sharp blades and according to an online study, although the Feather blade is slightly sharper on first use, the Bic DE blades are actually sharper than the Feather blades second use on first use. These blades were tested on a machine designed to measure sharpness. I usually throw my blades away after two or three uses. I will use them at least five times before giving up. I could probably use them longer but at the current price per blade why risk potential micro trauma. I like to use them in a soft razor for an efficient yet comfortable shave. However, if you have steel wool on your bristles and like aggressive razors, I'm sure these blades will get the job done effectively, especially on second and third uses as they actually get sharper after the first use. There is probably nothing hotter. than a Feather blade on first use, but if you don't mind waiting until the second shave for an even sharper feel, these Bic DE blades are a real find and, for now at least, are great value and last longer . standing edge of the blade. But don't take my word for it. Just buy a pack and try it. While experienced razors know that no brand of blade works well with all razors, if you like Feather, Gillette Nacet and similarly sharp blades in your razor, I suspect that you will like Bic Chrome Platinum DE blades because they work well and fit a great price.
