The razor with four blades consists of a handle 1, the head 2, the four blades 3, a mechanism for changing the inclination 4, a pressure point for changing the inclination 5. The novelty of the device is that it has a mechanism for changing the inclination 4. The four blades are mounted two on each side used in shaving. Thus having used the two blades on one side and once these have become worn through use, the point 5 is pressed until point 8 reaches point 10. While the initial position of the inclination of the blades used was at point 7 it is now at point 9. |
