I just purchased a vintage John Cockhill smiling razor with Sheffield steel. First sheffield I have owned. The razor edge was the sharpest I have seen on any of my razors vintage or modern. The shave was smooth as silk. I really was wondering why the difference and you guys have made my day. Under a 300 power scope the bevelAttachment 246283 is really smooth. I am posting a picture because the razor blade looks like it is new.
