I'm curious about the B-20 Proline (that I just won a pack of) as compared to the Schick (Chick) blades that have a keyed dispenser. I don't own a microscope so I was wearing three pair of reading glasses trying to compare the two. Is the bevel the same or is there a difference? I know @Bird Lives has already tried them with great success and I think a few others have as well; maybe @Jayaruh and/or @EzraCobb if I remember correctly. Maybe @John Ruschmeyer too. I just loaded a few into an empty dispenser and then popped one in a J handle Schick for tomorrow's shave.
