Abstract

Shaving systems are disclosed that include (a) a handle having a distal end and a proximal end; and (b) a shaving assembly, disposed at the distal end of the handle, the shaving assembly including a blade unit comprising a plurality of blades disposed in a housing, the housing having a front cutting side and an opposite rear side and a plurality of measurement elements on a trailing edge of the rear side.

First claim

What is claimed is:

1. A method of shaving comprising
providing a shaving system having a blade unit, and a handle on which the blade unit is pivotably mounted, the blade unit comprising a plurality of blades disposed in a housing with the length of each of the blades disposed perpendicular to the length of the handle, the housing having a front cutting side and an opposite rear non-cutting side, and a plurality of measurement elements on a trailing edge of the rear side of the housing, wherein the handle extends from a central portion of the rear non-cutting side of the blade unit, and a lubricating strip disposed adjacent the trailing edge on the front cutting side of the housing, wherein the measurement elements comprise openings positioned facing directly away from the front cutting side so that portions of the lubricating strip are visible through the openings during shaving, and wherein the housing is a first color and the lubricating strip is a second, different color;
utilizing the measurement elements to measure a dimension of a facial hair feature; and
contacting the skin with the blades to remove a portion of the facial hair from the skin by shaving, so as to sculpt the outline of the facial hair feature based on the measured dimension.

2. The method of claim 1 , wherein the facial hair feature is a sideburn or a portion of a mustache.

3. The method of claim 2 , wherein the dimension is width.

4. The method of claim 2 , further comprising comparing the dimension of the sideburn or mustache with a corresponding dimension of an opposite sideburn or portion of the mustache.

5. The method of claim 1 , wherein the measurement elements are regularly spaced along the trailing edge of the blade unit from a first lateral side of the housing to a second lateral side of the housing.

6. The method of claim 1 , wherein the openings are arrow shaped or triangular.

7. The method of claim 1 , wherein the blade unit is removably mounted on the handle by an interface element on which the blade unit is pivotably mounted.
