Abstract

A back shaver handle has a generally s-shaped elongated member. A grip has a finger surface located on the inner side. A blade attachment at a blade end is located on the inner side. A body leverage surface is located on an outer side of the elongated member near a midway between the grip and the blade end configured to press a body leverage surface against a user's forearm when a finger surface and grip are respectively gripped by fingers and hand with thumb facing away from the blade end of a same arm of the user and the s-shaped elongated member is reaching the blade end under an armpit of the same arm of the user to leverage the blade attachment located on the inner side of the elongated member towards a torso backside of the user.

Claims (30)

1. A method of using a back shaver handle, comprising:

(a) obtaining a back shaver handle comprising a grip end of a generally s-shaped elongated member having a body defining an inner side and an outer side, the outer side opposite the inner side, and a blade attachment at a blade end of the generally s-shaped elongated member, and a midway located between the grip end and the blade end, wherein the generally s-shaped elongated member is shaped with a body leverage surface on the inner side, the body leverage surface located between the blade end and the midway of the generally s-shaped elongated member, the blade end located on the inner side opposite the grip end, the blade attachment configured to hold a cartridge with a sharp blade in a way that allows the sharp blade to face away from the inner side of the generally s-shaped elongated member;

(b) gripping fingers of a hand of a user on the grip end with a thumb of the hand pointed away from the blade end of the generally s-shaped elongated member;

(c) pressing the body leverage surface against a forearm of the user when the grip end is gripped by the fingers of the hand by a same arm as the forearm of the user;

(d) positioning the generally s-shaped elongated member under an armpit of the user reaching the blade end under an armpit of the same arm of the user to leverage the blade attachment located on the inner side of the generally s-shaped elongated member against a torso backside of the user; and

(e) leveraging the generally s-shaped elongated member using the forearm and the body leverage surface as a fulcrum relative to the grip end to press the blade end towards the torso backside of the user.

2. A method of using a back shaver handle according to claim 1 , wherein the body leverage surface comprises a soft cushion attached thereto and wherein said step (c) of pressing comprises the step of (c)(1) pressing the soft cushion attached to the body leverage surface against the user's forearm arm.

3. A method of using a back shaver handle according to claim 2 , wherein the soft cushion pressed in said step (c)(1) is curved such that it meshes with a curve of the body leverage surface on the inner side of the generally s-shaped elongated member near the midway between the grip end and the blade attachment.

4. A method of using a back shaver handle according to claim 2 , wherein the soft cushion comprises a flexible sponge attached to the body leverage surface pressed against the user's forearm arm.

5. A method of using a back shaver handle according to claim 4 , wherein the method further comprises the step of (g) reversing the fingers and the hand at the grip end and the generally s-shaped elongated member reaches the soft cushion against a torso backside of the user and the flexible sponge has characteristics capable of holding a skin care product for application to the torso backside of the user.

6. A method of using a back shaver handle according to claim 5 , wherein the flexible sponge comprises strap, the method further comprises the step of (h) attaching the strap of the flexible sponge to the elongated member near the body leverage surface to adhere the sponge to the elongated member.

7. A method of using a back shaver handle according to claim 1 , wherein the method further comprises the steps of:

(g) attaching a flexible sponge to the body leverage surface on the outer side of the generally s-shaped elongated member near the midway between the grip end and the blade attachment;

(h) absorbing a skin care product into the flexible sponge;

(i) reversing the fingers and the hand at the grip end;

(j) gripping with a thumb of the hand facing away from the blade end of the generally s-shaped elongated member;

(k) positioning the generally s-shaped elongated member under an armpit of the user reaching the blade end and the flexible sponge under an armpit of the same arm of the user to leverage the flexible sponge on the body leverage surface on the outer side of the generally s-shaped elongated member against a torso backside of the user; and

(l) stroking the flexible sponge against the torso backside of the user.

8. A method of using a back shaver handle according to claim 1 , further comprising the step of (g) attaching the blade attachment to a safety razor with a sharp edge of at least one sharp blade on the inner side of the elongated member facing against the torso backside of the user.

9. A method of using a back shaver handle according to claim 1 , wherein the elongated member comprises a hinge and a finger release located near the hinge the inner surface of the elongated member, further comprising the step of (g) pressing the finger release.

10. A method of using a back shaver handle according to claim 1 , wherein the elongated member comprises a hinge near the midway of the generally s-shaped elongated member, the midway located between the grip end and the blade attachment, further comprising the step of (g) folding the generally s-shaped elongated member at the hinge.

11. A method of using a back shaver handle according to claim 10 , wherein the body leverage surface is located between the hinge and the grip end on the outer side of the elongated member.

12. A method of using a back shaver handle according to claim 10 , wherein in said step (g) the elongated member is folded at the hinge back against itself for storage.

13. A method of using a back shaver handle according to claim 10 , wherein in said step (g) the elongated member is folded at the hinge approximately 180 degrees to completely fold the elongated member back against itself for storage and reduce a length of the elongated member by approximately half.

14. A method of using a back shaver handle according to claim 1 , wherein a cross-sectional shape of the elongated member has a shape that is substantially round or oval.

15. A method of using a back shaver handle according to claim 1 , further comprising the steps of

(f), attaching the blade attachment to a safety razor on the inner side of the elongated member, the safety razor comprising a sharp edge of at least one flexible sharp blade comprising a sharp edge facing against the torso backside of the user, and an outer comb comprising an inside edge, and an inner guard comprising an inner guard edge and a trailing opening inside of inner guard edge and a sharp blade and a leading opening inside an inside edge of outer comb and a sharp blade; and

(f) stroking safety razor while attached to the blade end against the torso backside of the user.

16. A method of using a back shaver handle according to claim 15 , wherein the sharp edge of the flexible sharp blade longitudinally bends relatively more parallel to a skin surface when the generally s-shaped elongated member presses the inside edge and the inner guard edge of the safety razor into the skin surface during shaving of hair.

17. A method of using a back shaver handle according to claim 1 , wherein the generally s-shaped elongated member gripped in said step (a) is shaped with the body leverage surface as a convex shape on the inner side, the convex shape located between the blade receiving end and a midway, the midway located between the grip end and the blade attachment of the generally s-shaped elongated member.
