A shovel for snow, dirt or other product comprises a main shovel handle having a main hand grip and a main pole which is attached to a blade; and an auxiliary handle having an auxiliary hand grip and an auxiliary pole. According to one aspect, the auxiliary pole has a threaded end which is received in a threaded bore in the main pole. The auxiliary pole can be easily attached and detached from the main pole. Adhesive can also be used. According to further aspects, a separate connecting device connects the auxiliary pole to the main pole. In one further aspect, the connecting device has a first branch threadably attached to the main pole, a second branch threadably attached to the auxiliary pole, and a third branch threadably attached to the blade. The connecting device could also be formed as a cuff or sleeve and entirely surround the main pole and be attached thereto such as with a screw, or could be formed in a semicircular cuff and be attached to the main pole such as with bands or clamps. In any case the auxiliary pole can be easily connected to the main pole.

1. A shovel, comprising a main handle having (i) a main pole, (ii) a main hand grip attached at one end of the main pole, and (iii) a blade attached at another end of the main pole;an auxiliary handle having (i) an elongated auxiliary pole, and (ii) an auxiliary hand grip at one end of the auxiliary
1. A shovel, comprising a main handle having (i) a main pole, (ii) a main hand grip attached at one end of the main pole, and (iii) a blade attached at another end of the main pole;an auxiliary handle having (i) an elongated auxiliary pole, and (ii) an auxiliary hand grip at one end of the auxiliary pole; anda separate connecting device removably securing the auxiliary pole to the main pole, said separate connecting device comprising an elongated, flexible, C-shaped sleeve circumferentially surrounding more than half or the main pole, with an inside surface closely receiving the main pole, means for removably securing the sleeve to the main pole to prevent the sleeve from moving with respect to the main pole, and means for securing the other end of the auxiliary pole to the connecting device, wherein said securing means for the sleeve includes at least one band surrounding said sleeve and preventing said connecting device from moving relative to said main pole. 2. The shovel as in claim 1, wherein said sleeve has an inside surface configuration substantially matching an external surface configuration of the main pole, said sleeve extending longitudinally along an extent of said main pole to enable said inside surface configuration of said sleeve to be in surface-to-surface contact with said external surface configuration of said main pole. 3. The shovel as in claim 1, further including nubs projecting away from said inside surface of said sleeve and contacting said main pole to prevent said connecting device from moving with respect to said main pole. 4. The shovel as in claim 1, wherein said auxiliary pole is formed unitary, in one piece with said connecting device. 5. The shovel as in claim 1, wherein said auxiliary pole comprises a single piece extending from one end to said other end. 6. The shovel as in claim 1, wherein the band can be tensioned around the sleeve, and the flexibility of the sleeve allows the sleeve to be tightly drawn against the main pole. 7. The shovel as in claim 1, wherein the connecting device is secured to the main pole proximate the blade, and the auxiliary pole extends at an acute angle relative to the main pole, and has a length such that when the user manually grasps the main hand grip with one hand and the auxiliary hand grip with the other hand during the shoveling process, the auxiliary hand grip provides significant leverage to minimize bending of the torso by the user. 8. The shovel as in claim 7, wherein the auxiliary pole extends at an angle of 40 to 60 degrees relative to the main pole, and the length of the auxiliary pole is about 70 percent of the length of the main pole. 9. A shovel attachment, comprising:an auxiliary handle having (i) an elongated auxiliary pole, and (ii) an auxiliary hand grip at one end of the auxiliary pole; anda connecting device at another end of the auxiliary pole for securing the auxiliary pole to a main pole, said connecting device comprising an elongated, flexible, C-shaped sleeve secured via securing means unitary with the other end of said auxiliary pole and extending circumferentially more than one hundred and eighty degrees, and means for removably securing the sleeve to the main pole to prevent the sleeve from moving with respect to the main pole, wherein said securing means for the sleeve includes at least one band for surrounding the main pole, the band being tensionable to draw the sleeve around the main pole. 10. The shovel attachment as in claim 9, wherein the sleeve has a cylindrical inside surface. 11. The shovel attachment as in claim 9, wherein the band is attached to the sleeve. 12. The shovel attachment as in claim 9, further including nubs projecting away from the inside surface of said sleeve for contacting the main pole to prevent said connecting device from moving with respect to the main pole. 13. The shovel attachment as in claim 9, wherein the auxiliary pole extends at an angle of 40 to 60 degrees relative to a longitudinal axis of th e connecting device. 14. A shovel, comprising a main handle having (i) a main pole (ii) a main band grip attached at one end of the main pole, and (iii) a blade attached at another end of the main pole;an auxiliary handle having (i) an elongated auxiliary pole, and (ii) an auxiliary hand grip at one end of the auxiliary pole; anda separate connecting device removably securing the auxiliary pole to the main pole, said separate connecting device comprising an elongated, flexible, C-shaped sleeve with an inside surface closely receiving the main pole and circumferentially surrounding more than one hundred and eighty degrees of the main pole, means for removably securing the sleeve to the main pole to prevent the sleeve from moving with respect to the main pole, and means for securing the other end of the auxiliary pole to the connecting device,wherein the connecting device is secured to the main pole proximate the blade, and the auxiliary pole i) is retained by the connecting device at an acute angle relative to the main pole, and ii) has a length, such that when the user manually grasps the main hand grip with one hand and the auxiliary hand grip with the other hand during the shoveling process, the auxiliary hand grip provides significant leverage to minimize bending of the torso by the user, wherein said securing means for the sleeve includes at least one band for surrounding the main pole, the band being tensionable to draw the sleeve around the pole. 15. The shovel as in claim 14, wherein the sleeve has a cylindrical inside surface. 16. The shovel as in claim 14, wherein the band is attached to the sleeve. 17. The shovel as in claim 14, further including nubs projecting away from the inside surface of said sleeve for contacting the main pole to prevent said connecting device from moving with respect to the main pole. 18. The shovel as in claim 14, wherein the auxiliary pole extends at an angle of 40 to 60 degrees relative to the main pole, and the length of the auxiliary pole is about 70 percent of the length of the main pole.
