I don't understand why this blade is as expensive as a Feather blade, which by most shavers is considered the sharpest blade. In my experience the Iridium Super shaves like a Derby on the first shave, which means average and like a Merkur on the second the shave, which means horrible. The blade is very similar to the Gillette Yellow. This blade is not smooth. My favorite blade is the Persona (Red Pack) because it is smooth and sharp. The Iridium has many loyal followers which once again proves YMMV!
