ABSTRACT:
To reduce the frictional resistance of a wet razor head, especially a razor blade unit thereof, as well as to provide a sharper blade without the risk of injury, there is provided a combination of a protective wire that covers a blade made of a steel strip having a width of less than 5 mm, a thickness between 0.05 and 0.25 mm, and a chromium/molybdenum steel composition having a hardness of greater than 620 HV and a retained austenite content of less than 32%, with the blade being a single piece that has no perforations or holes and that is mounted in a vibration-free manner in a plastic body. The protective wire comprises loops that are spaced greater than 2 mm but less than 5 mm apart and that have a minimum thickness of greater than 0.1 mm to form a protective guard over the razor blade with the effect of a protective foil.
