Made by the Feather Safety Razor Co in Japan these are the ultimate razor blades for sharpness. Described by some as the “assassins blade” of double edged safety razor blades. This blade is great for more experienced users.
These are excellent, sharp blades. I get a close and comfortable shave with Feathers. They are, however, not for beginners. I shaved for about a year with more forgiving blades before switching to Feather. And fast service from Groomatorium, too!
