Abstract
A razor head, especially in the form of a so-called razor blade unit, is disposed on the front end of a handle. A single or double razor blade rests in a fixed manner on a blade holder of a plastic housing. The razor blade or blades are fixedly secured on a spacer and form a blade holder that can essentially be inserted from above into the plastic housing onto the blade platform thereof. After insertion, the blade holder can be fixed in the plastic housing. For this purpose, either a fixation strip is placed upon the blade holder, or the plastic housing is plastically deformable in such a way that the blade holder is fixed in the plastic housing.
