One embodiment of a handle attachment assembly formed in accordance with the present invention is provided. The handle attachment assembly may be used for removably attaching a handle to an elongate shaft having a proximal end and a distal end. The handle attachment assembly may include a hand grip adapted to be gripped and held by a user and a clamp assembly. The clamp assembly may be coupled to the hand grip for removably attaching the hand grip to the elongate shaft between the proximal end and the distal end of the elongate shaft. The clamp assembly may include a first V-shaped clamp and a second V-shaped clamp. A fastening assembly may be used for driving the first V-shaped clamp toward the second V-shaped clamp to removably clamp the elongate shaft between the first and second V-shaped clamps.

The invention claimed is: 1. A handle attachment assembly for removably attaching a handle to an elongate shaft having a proximal end and a distal end, the handle attachment assembly comprising: a hand grip adapted to be gripped and held by a user; a clamp assembly coupled to the hand grip for removably attaching the hand grip to the elongate shaft between the proximal end and the distal end of the elongate shaft, the clamp assembly being attachable to the elongate shaft; one or more fasteners, each fastener having a proximal end and a distal end; and one or more elongated housings in the clamp assembly, wherein each of the one or more elongated housings extends by a first length from a surface portion of the clamp assembly facing the hand grip, each of the elongated housings extending toward the hand grip and each of the one or more elongated housings configured to receive one of the one or more fasteners, the first length being at least equal to a second length of the fastener extending from the surface portion such that the entire distal end of the fastener is at least partially enclosed within the elongated housing to impede injury from contact with the distal end of the fastener when the handle attachment assembly is coupled to the elongate shaft. 2. The handle attachment assembly as claimed in claim 1, wherein, the clamp assembly includes a first V-shaped clamp and a second V-shaped clamp, and each of the one or more fasteners is configured to drive the first V-shaped clamp toward the second V-shaped clamp to removably clamp the elongate shaft between the first and second V-shaped clamps. 3. The handle attachment assembly of claim 2, wherein the second V-shaped clamp includes one or more raised ribs protruding outward from a clamping surface of the second V-shaped clamp. 4. The handle attachment assembly of claim 3, wherein the one or more raised ribs protruding outward from the clamping surface of the second V-shaped clamp are oriented substantially perpendicular to a longitudinal length of the elongate shaft when the handle attachment assembly is coupled to the elongate shaft. 5. The handle attachment assembly of claim 4, wherein the one or more raised ribs protrude outward from the clamping surface of the second V-shaped clamp greater than 0.5 millimeters. 6. The handle attachment assembly of claim 2, wherein the first V-shaped clamp includes a clamping surface for engaging the elongate shaft, wherein the clamping surface is comprised of a first planar clamping surface and a second planar clamping surface, and wherein the first planar clamping surface is oriented greater than 90 degrees from the second planar clamping surface. 7. The handle attachment assembly of claim 1, wherein the hand grip is attached to the clamp assembly such that when the clamp assembly is removably coupled to the elongate shaft, the hand grip extends greater than 15 centimeters from the elongate shaft. 8. The handle attachment assembly of claim 1, wherein the hand grip is attached to the clamp assembly such that when the clamp assembly is removably coupled to the elongate shaft, the hand grip is oriented perpendicular to the elongate shaft. 9. The handle attachment assembly of claim 1, wherein, each of the one or more fasteners is a threaded fastener, and each of the one or more fasteners is rotatable to tighten or loosen the clamp assembly about the elongate shaft. 10. The handle attachment assembly of claim 2, wherein the second V-shaped clamp includes a clamping surface for engaging the elongate shaft, wherein the second V-shaped clamp assembly engages the elongate shaft at a plurality of pressure points. 11. The handle attachment assembly of claim 1, wherein the clamp assembly is adapted to couple to elongate shafts having diameters between about 2 centimeters and about 4 centimeters. 12. The handle attachment assembly of claim 1, wherein the hand grip has a diameter of greater than 2 centimeters and includes a plurality of finger indentations each adapted to receive a finger of the user. 13. The handle attachment assembly of claim 2, wherein the first V-shaped clamp has a first clamping surface and a second clamping surface inclined from one another by a first predetermined angle, wherein the second V-shaped clamp has a first clamping surface and a second clamping inclined from one another by a second predetermined angle, wherein the first predetermined angle is different than the second predetermined angle by more than about five degrees. 14. The handle attachment assembly of claim 7, wherein the hand grip is attached to the clamp assembly such that when the clamp assembly is removably coupled to the elongate shaft, the hand grip is oriented perpendicular to the elongate shaft. 15. The handle attachment assembly of claim 2, wherein the first V-shaped clamp is integrally formed with the hand grip. 16. The handle attachment assembly of claim 1, wherein a structural web extends between any two or more of the elongated housings. 17. The handle attachment assembly of claim 1, wherein a structural web extends between two support arms which couple the hand grip to the clamp assembly. 18. The handle attachment assembly of claim 16, wherein the structural web extends between any two or more of the elongated housings and between two support arms which couple the hand grip to the clamp assembly. 19. The handle attachment assembly of claim 1, wherein each of the one or more elongated housings are configured to surround one of the one or more fasteners between the proximal end of the fastener and the distal end of the fastener. 20. The handle attachment assembly of claim 1, wherein a base section of each of the elongated housings has side walls configured to receive the sides of a nut configured to engage in threaded engagement with one of the one or more fasteners, and wherein the side walls are configured to prevent a rotation of the nut.
