These razors were produced between 1984 and 1998. I've only owned one so far so I can't comment on how each style shaves. What they all share in common is a razor head that is rectangular in shape.
Style 1 - produced from 1984 to at least 1990. This one is also referred to as an N1 using the Appleby designations.
