1. A trimmer handle, comprising: an elongated tubular attachment rod having a length axis, a rod proximate end and a rod distal end, wherein said rod distal end includes first rod holes and second rod holes;a first clamp plate having a concave first proximate end extending parallel with said axis, a first distal end, and a partial-cylindrical-shaped first clamping surface disposed between said first proximal end and said first distal end and extending perpendicular to said axis;a second clamp plate having a concave second proximate end extending parallel with said axis a second distal end, and a partial-cylindrical-shaped second clamping surface disposed between said second proximal end and said second distal end and extending perpendicular to said axis;a unitary hand grip on said rod proximate end having an integral hand guard;a first fastener passing through said first rod holes, through said first clamp plate, and through said second clamp plate;a second fastener passing through said second rod holes, through said first clamp plate, and through said second clamp plate; and,a third fastener attaching said first distal end of said first clamp plate to said second distal end of said second clamp plate;wherein said attachment rod is captured in said concavity of said first proximate end and said concavity of said second proximate end; and,wherein said first clamp plate and said second clamp plate are adapted to simultaneously attach said attachment rod to a trimmer shaft such that said trimmer shaft extends perpendicular to said attachment rod. 2. The trimmer handle according to claim 1, wherein said hand grip is press fit to said attachment rod. 3. The trimmer handle according to claim 1, wherein said hand grip includes at least one finger relief groove. 4. The trimmer handle according to claim 1, wherein said first clamp plate and said second clamp plate are mirror-imaged elements comprised of stamped metal. 5. The trimmer handle according to claim 4, wherein said first clamp plate partial-cylindrical-shaped clamping surface is configured to clamp around a shaft housing of a trimmer. 6. The trimmer handle according to claim 5, wherein said first fastener includes a bolt, a washer, and a nut. 7. A grass trimmer handle, comprising: an elongated tubular attachment rod having a length axis, a rod proximate end and a rod distal end with a first pair of aligned rod holes and second pair of aligned rod holes;a first clamp plate having a concave first proximate end extending parallel with said axis, a first distal end, and a partial-cylindrical-shaped first clamping surface extending perpendicular to said axis;a second clamp plate having a concave second proximate end extending parallel with said axis, a second distal end, and a partial-cylindrical-shaped second clamping surface extending perpendicular to said axis;a unitary soft hand grip having finger relief groove and an integral hand guard, said hand grip press-fit to said rod proximate end;a first bolt passing through said first pair of aligned rod holes, through said first clamp plate, and through said second clamp plate; and,a second bolt passing through said second pair of aligned rod holes, through said first clamp plate, and through said second clamp plate;wherein said first bolt and said second bolt attach said first clamp plate and said second clamp plate to said attachment rod;wherein said attachment rod is captured in said concavity of said first proximate end and said concavity of said second proximate end; and,wherein said first clamp plate and said second clamp plate are adapted to simultaneously attach said attachment rod to a trimmer shaft such that said trimmer shaft extends perpendicular to said attachment rod. 8. The trimmer handle according to claim 7, wherein said first clamp plate and said second clamp plate are mirror-imaged elements comprised of stamped metal. 9. A trimmer, comprising: a trimmer shaft housing;an elongated tubular attachment rod having a length axis, a rod proximate end and a rod distal end, wherein said rod distal end includes first rod holes and second rod holes;a first clamp plate having a concave first proximate end extending parallel with said axis and attached to said attachment rod, a first distal end, and a partial-cylindrical-shaped first clamping surface extending perpendicular to said axis and disposed around said trimmer shaft housing;a second clamp plate having a concave second proximate end extending parallel with said axis and attached to said attachment rod, a second distal end, and a partial-cylindrical-shaped second clamping surface extending perpendicular to said axis and disposed around said trimmer shaft housing;a unitary hand grip on said rod proximate end, said hand grip having an integral hand guard;a first fastener passing through said first rod holes and attaching said first clamp plate and said second clamp plate to said attachment rod;a second fastener passing through said second rod holes and attaching said first clamp plate and said second clamp plate to said attachment rod; anda third fastener attaching said first distal end of said first clamp plate to said second distal end of said second clamp plate;wherein said attachment rod is captured in said concavity of said first proximate end and said concavity of said second proximate end; and,wherein said first clamp plate and said second clamp plate are adapted to simultaneously attach said attachment rod to said trimmer shaft housing such that said trimmer shaft extends perpendicular to said attachment rod. 10. The trimmer according to claim 9, wherein said hand grip is press fit to said attachment rod. 11. The trimmer according to claim 9, wherein said hand grip includes at least one finger relief groove. 12. The trimmer according to claim 9, wherein said first clamp plate and said second clamp plate are mirror-imaged elements comprised of stamped metal. 13. The trimmer according to claim 9, wherein said first fastener includes a bolt, a washer, and a nut. 14. The trimmer according to claim 9, wherein said trimmer is a grass trimmer. 15. The trimmer according to claim 9, wherein said trimmer is gas powered. 16. The trimmer according to claim 9, wherein said trimmer is battery powered. 17. The trimmer according to claim 9, wherein said trimmer is electric powered.
