So I started out using feathers and I enjoyed the shaves.... Recently, I purchased a sampler pack and tried Astra and the gillette super platium blue and loved every second. Not as sharp as the feather but a very smooth shave.
Yes. They are close to as sharp, though. Recently I tried the Feathers again, and although I like them better this time around, I still prefer the Gillette Super Plats. My bulk blade is the Black (India), but I can't tell much difference from the Blue.
