It's strange, lots of people characterise them as not very sharp but for me they shave like they are sharp. I have thick dense stubble and they only pull if I have four or five days growth. They give me as close a shave as any other blades I've tried (subjectively) or closer and they are comfortable, they also last 5 shaves with ease. Feathers which are apparently sharp shave me no closer and are as rough as a dog's arse on the first shave, okayish on the second and then back to rough.
