The MERKUR Progress 500 stands for maximum variability. Even then in the
1950s, it was one of the first safety razors with an adjustable blade gap.
Since you also adjust the setting angle of the razor blade, you can adjust
the thoroughness of the shave to your own personal taste. With the short
handle, you gain freedom of movement in complex facial and body areas.
You can adjust the distance between blade and comb with a quick rotation of
the handle. This way you can tune the thoroughness of the shave to your
personal preference. For example, you can work long hair with a large blade
gap, while the daily facial shave can be done with a gentle blade setting.
