What is claimed is: 1. A shock absorbing shovel assembly comprising; a blade secured to a first end of an elongated handle; a shock absorbing cartridge having a first end secured to a second end of said elongated handle, said shock absorbing cartridge having a biasing member therein said shock absorbing cartridge including an annular shaped substantially rigid outer casing member having a first end and a second end, said outer casing member constructed and arranged to enclose said biasing member, said first end of said outer casing member including an integrally formed socket constructed and arranged to cooperate with said second end of said elongated handle in an overlapping, telescoping and non-rotational relationship; a handgrip connected to a second end of said shock absorbing cartridge; whereby said biasing member compresses during use of said shovel to reduce impact shock. 2. The shock absorbing shovel assembly of claim 1 wherein said biasing member is a coil spring. 3. The shock absorbing shovel assembly of claim 1 wherein said biasing member is constructed of a polymeric material. 4. The shock absorbing shovel assembly of claim 1 wherein said second end of said outer casing member includes an integrally formed boss, wherein said boss is constructed and arranged to interlockingly engage a corresponding socket formed into said handgrip resulting in a overlapping mechanically secure connection therebetween. 5. The shock absorbing shovel assembly of claim 4 wherein said second end of said outer casing member and said handgrip are constructed and arranged for snap-together assembly without additional fasteners. 6. The shock absorbing shovel assembly of claim 4 wherein said handgrip is substantially D-shaped oriented transverse with respect to a longitudinal axis of said elongated handle. 7. The shock absorbing shovel assembly of claim 4 wherein said handgrip is formed as a unitary member through the process of injection molding. 8. The shock absorbing shovel assembly of claim 1 wherein said blade is a curved blade including a leading edge, a rear edge and two distal ends, wherein said blade includes a centrally located spine integrally formed thereto and extending transverse with respect to said leading edge, said spine constructed and arranged to cooperate with first end of said elongated handle in an interlocking manner. 9. The shock absorbing shovel assembly of claim 8 wherein said distal ends of said blade each include an integrally formed gusset constructed and arranged to maintain the curvature of said blade. 10. The shock absorbing shovel assembly of claim 9 wherein said gussets extend substantially from said leading edge to about said rear edge. 11. The shock absorbing shovel assembly of claim 8 wherein said leading edge includes a shock absorbing wear member, wherein said shock absorbing wear member extends substantially across said leading edge, whereby said shock absorbing wear member flexes during use of said shovel to reduce impact shock. 12. The shock absorbing shovel assembly of claim 11 wherein said shock absorbing wear member is constructed and arranged to torsionally pivot with respect to said blade during use of said shovel. 13. The shock absorbing shovel assembly of claim 11 wherein said shock absorbing wear member includes at least one upwardly extending mounting boss constructed and arranged to cooperate with said blade for attachment thereof, whereby said at least one mounting boss is constructed and arranged to flex during use of said shovel for absorbing impact shock. 14. The shock absorbing shovel assembly of claim 11 wherein said shock absorbing wear member is removable and replaceable. 15. The shock absorbing shovel assembly of claim 11 wherein said shock absorbing wear member is constructed of polymeric material. 16. The shock absorbing shovel assembly of claim 11 wherein said shock absorbing wear member is constructed of polycarbonate plastic. 17. The shock absorbing shovel assembly of claim 1 wherein said blade, said handgrip and said outer casing member are formed through the process of injection molding. 18. The shock absorbing shovel assembly of claim 1 wherein said elongated handle is constructed of metal having an outer layer of polymeric material. 19. A shock absorbing shovel assembly comprising; a blade secured to a first end of an elongated handle, said blade being a curved blade including a leading edge, a rear edge and two distal ends, wherein said blade includes a centrally located spine integrally formed thereto and extending transverse with respect to said leading edge, said spine constructed and arranged to cooperate with first end of said elongated handle in an interlocking manner, said leading edge including a shock absorbing wear member, wherein said shock absorbing wear member extends substantially across said leading edge, whereby said shock absorbing wear member flexes during use of said shovel to reduce impact shock, said shock absorbing wear member including at least one upwardly extending mounting boss constructed and arranged to cooperate with said blade for attachment thereof, said at least one mounting boss constructed and arranged to flex during use of said shovel for absorbing impact shock; a shock absorbing cartridge having a first end secured to a second end of said elongated handle, said shock absorbing cartridge having a biasing member therein; a handgrip connected to a second end of said shock absorbing cartridge; whereby said biasing member compresses during use of said shovel to reduce impact shock.
