Flexible back shaver

1. A back shaver, comprising:

an elongated back shaver handle defining an inner side and an outer side and a blade end and a handle end, the outer side opposite the inner side, the blade end opposite the handle end;

a grip defined by at one of the inner and outer sides at the handle end of the elongated back shaver handle; and

a coupling having a first side and a second side opposite the first side, the first side of the coupling coupled to the inner side at the blade end of elongated back shaver handle; and

a blade cartridge comprising a sharp blade with a sharp edge, the blade cartridge coupled to the second side of the coupling with the sharp edge of the sharp blade to face away from the inner side of the elongated back shaver handle, wherein the blade cartridge further comprises an outer comb comprising an inside edge, and an inner guard comprising an inner guard edge and a trailing opening between inner guard edge and the sharp blade and a leading opening inside of the inside edge of outer comb and the sharp blade; and

wherein the coupling allows for the cartridge to move in relation to the elongated back shaver handle.

2. A back shaver according to claim 1 , wherein the coupling comprises a material that would allow the blade cartridge to pivot with respect to the elongated back shaver handle.

3. A back shaver according to claim 1 , wherein the coupling comprises rubber or another flexible material.

4. A back shaver according to claim 1 , wherein the coupling is a pivot member allowing the blade cartridge to pivot in relation to the elongated back shaver handle.

5. A back shaver according to claim 4 , wherein the pivot member is located at least on the blade cartridge.

6. A back shaver according to claim 4 , wherein the pivot member is located on at least the inner side at the blade end of elongated back shaver handle.

7. A back shaver according to claim 4 , wherein the pivot member is a ball protrusion on the blade cartridge, the elongated back shaver handle having a recessed socket to receive the ball protrusion to define a ball joint.

8. A back shaver according to claim 7 , wherein the recessed socket tapers narrower as it extends away from the blade cartridge.

9. A back shaver according to claim 7 , wherein the sharp blade is a flexible sharp blade, wherein the sharp edge faces away from the inner side of the elongated back shaver handle, and wherein the sharp edge of the sharp blade longitudinally bends relatively more parallel to a skin surface when the elongated back shaver handle presses the inside edge and the inner guard edge of the blade cartridge into the skin surface during shaving of hair.

10. A back shaver according to claim 1 , wherein the blade cartridge comprises another sharp blade spaced from and parallel to the sharp blade, wherein the another sharp blade comprises another sharp edge facing away from the inner side of the elongated back shaver handle, and further comprises another outer comb comprising another inside edge, and another inner guard comprising another inner guard edge and another trailing opening between another inner guard edge and the another sharp blade and another leading opening inside of the another inside edge of the another outer comb and the another sharp blade.

11. A back shaver according to claim 1 , wherein the blade cartridge comprises another sharp blade spaced from and parallel to the sharp blade with the another sharp edge of the another sharp blade facing away from the inner side of the elongated back shaver handle.

12. A back shaver according to claim 1 , wherein the coupling allows for the cartridge to move radially in relation to the elongated back shaver handle.
