First shave today with the Parker Platinum blade this A.M. It impressed me with the smoothness & medium sharpness. It reminded me of a Lab Blue blade & not a Derby Premium. I received a DFS with no nicks. Its a most pleasant blade for my medium beard type. I used a Yaqi Cobbed razor. Its not a top tier blade but, worked very good for me. I don't think it will work for heavy beard types although I could be wrong.
