1. A hand held scraper for removing debris from a surface, wherein the hand held scraper comprises: a body;a handle attached to the body; anda plurality of cantilever abraders that are flexible and capable of independently moving relative to one another, wherein at least two of the cantilever abraders comprises: a cantilever body hinged to and extending from the body; anda scraping member depending from an underside of the cantilever body, the scraping member having a scraping edge positioned on an end of the scraping member for scraping a surface;wherein the scraping edge of at least one of the plurality of cantilever abraders overlaps with an adjacent cantilever abrader scraping edge so as to substantially prevent passage of debris therebetween. 2. The hand held scraper of claim 1, wherein at least two of the plurality of cantilever abraders further comprises a support flange that projects from a lower surface of the cantilever abraders and functions to reinforce the scraping edge, wherein a first support flange portion of a first cantilever abrader overlaps with a second support flange portion of an adjacent second cantilever abrader to substantially prevent passage of debris between the first and second adjacent cantilever abraders. 3. The hand held scraper of claim 1, wherein the plurality of cantilever abraders are arranged along a perimeter of a front portion of the body. 4. The hand held scraper of claim 1, wherein the plurality of cantilever abraders are positioned adjacent to one another and form an arrow shaped configuration. 5. The hand held scraper of claim 1, wherein a first surface of at least one cantilever abrader nests with a second surface of an adjacent cantilever abrader. 6. The hand held scraper of claim 1, further comprising a plurality of scraper projections positioned adjacent to the plurality of cantilever abraders, wherein the scraper projections extend from a lower surface of the body. 7. The hand held scraper of claim 6, wherein a first scraper projection intersects a second adjacent scraper projection. 8. The hand held scraper of claim 6, wherein the plurality of scraper projections substantially covers an area of the lower surface selected from the group consisting of a rear region of the lower surface, a middle region of the lower surface, and a combination thereof. 9. The hand held scraper of claim 6, wherein the cantilever abraders and the scraper projections substantially covers the entire lower surface. 10. The hand held scraper of claim 1, further comprising a shield attached to the body and positioned in front of the handle, wherein the shield comprises a surface capable of deflecting debris away from the handle. 11. The hand held scraper of claim 10, wherein the shield and handle define a through hole in the body sized to facilitate the removal of debris. 12. The hand held scraper of claim 1, further comprising a notch formed on a perimeter of the body, wherein the notch is configured and adapted to receive a windshield wiper blade. 13. The hand held scraper of claim 1, further comprising a set of flexible bristles mounted to the body, wherein the bristles are collectively arranged to form a substantially water impermeable barrier. 14. A hand held scraper for removing debris from a surface, wherein the hand held scraper comprises: a body;a handle attached to the body; anda plurality of cantilever abraders that are flexible and capable of independently moving relative to one another, wherein at least one of said cantilever abraders comprises: a cantilever body hinged to and extending from the body;a scraping member depending from an underside of the cantilever body, the scraping member having a scraping edge positioned on an end of the scraping member for scraping a surface; andtwo support flanges connected to the scraping member that reinforce the scraping edge. 15. The hand held scraper of claim 14, wherein at least one of the cantilever abraders has a displacement range up to about 0.375 inches. 16. The hand held scraper of claim 14, further comprising a plurality of scraper projections positioned adjacent to the plurality of cantilever abraders, wherein each of the plurality of scraper projections extends downwards from a lower surface of the body. 17. The hand held scraper of claim 16, wherein a first scraper projection intersects an adjacent second scraper projection. 18. The hand held scraper of claim 14, further comprising a shield attached to the body and positioned in front of the handle, wherein the shield comprises a surface capable of deflecting debris away from the handle. 19. The hand held scraper of claim 14, further comprising a notch formed on a perimeter of the body, wherein the notch is configured and adapted to receive a windshield wiper blade. 20. The hand held scraper of claim 14, further comprising a set of flexible bristles mounted to the body, wherein the bristles are collectively arranged to form a substantially water impermeable barrier. 21. A hand held ice scraper for removing ice from a surface, the ice scraper comprising: a body;a dome-shaped handle formed integrally with the body;a plurality of cantilever abraders that are flexible and capable of independently moving relative to one another, the cantilever abraders disposed at a front end of the body forward of the dome-shaped handle, each cantilever abrader comprising a cantilever finger extending from and hinged to the body and a scraping member depending from an underside of the cantilever finger, the scraping member having a scraping edge positioned on an end of the scraping member for scraping the surface, whereby the cantilever abraders will deflect upward due to the resistive pressure from the surface against which the scraping edges are pressed; anda plurality of non-cantilevered abraders each comprising a scraping member having a scraping edge depending from an underside of the body and positioned rearward of the plurality of cantilever abraders, at least some of the non-cantilevered abraders being positioned to the side of the dome-shaped handle.
