1. A hand held scraper for abrading a surface or removing a substance from a surface, wherein the scraper comprises: a body;a handle attached to said body;a first set of flexible cantilevered abraders capable of independently moving relative to one another, each flexible cantilevered abrader of the first set of flexible cantilevered abraders extending from the body in a first direction, wherein at least one cantilevered abrader of said first set comprise: a first end hinged to a surface of said body;a first groove defined in an upper surface of said cantilevered abrader for increasing the flexibility of said cantilevered abrader, wherein said first groove extends in a second direction along a width of said cantilever abrader and is positioned adjacent to and between said first end and an opposed second end; anda scraping edge disposed at a lower surface of the second end; andtwo substantially rigid members that extend from the body in the first direction and constrain a vertical range of motion of said first set of cantilevered abraders, wherein said first set of cantilever abraders are positioned adjacent to and between said two substantially rigid members. 2. The hand held scraper of claim 1, further comprising a second set of flexible cantilever abraders spaced apart from and facing an opposite direction of said first set of flexible cantilever abraders. 3. The hand held scraper of claim 1, further comprising a shield for deflecting substances, wherein said shield is positioned above said first set of cantilever abraders and wherein a lower edge of said shield further constrains said vertical range of motion of said cantilever abraders. 4. The hand held scraper of claim 3, further comprising a tapered notch positioned on an edge of said shield adapted for cleaning a windshield wiper blade. 5. The hand held scraper of claim 1, wherein said cantilever abrader further comprises a second groove defined in a lower surface of said cantilevered abrader and wherein said second groove extends along a width of said cantilever abrader and is positioned adjacent to said first end. 6. The hand held scraper of claim 1, further comprising a plurality of teeth positioned on a lower surface of said body capable of breaking-up hard substances. 7. The hand held scraper of claim 1, further comprising a scraper blade attached to said body and positioned adjacent to a respective one of said substantially rigid members. 8. The hand held scraper of claim 1, further comprising a liquid dispenser capable of dispensing a cleaning fluid, wherein said liquid dispenser is positioned within a cavity of said handle. 9. The hand held scraper of claim 1, further comprising a brush mounted to said body, wherein said brush comprises a plurality of bristles that are independently moveable relative to one another and wherein said bristles form a substantially water impermeable barrier. 10. A hand held scraper for abrading a surface or removing a substance from a surface, wherein the scraper comprises: a body;a handle attached to said body; anda plurality of flexible cantilevered abraders capable of independently moving relative to one another, each flexible cantilevered abrader of the plurality of flexible cantilevered abraders extending from the body in a first direction, wherein at least one cantilever abrader of said plurality of cantilevered abraders comprises: a first end hinged to a surface of said body;a first groove defined in an upper surface of said cantilevered abrader for increasing the flexibility of said cantilevered abrader;a second groove defined in an lower surface of said cantilevered abrader for increasing the flexibility of said cantilevered abrader, wherein said first and second grooves extend in a second direction along a width of said cantilever abrader and are positioned adjacent to and between said first end and an opposed second end; anda scraping edge disposed at a lower surface of the second end,wherein the thickness of said cantilever abrader between said first and second grooves is about 0.5 cm to about 1.5 cm to enable flexible vertically displacement of said cantilever abrader. 11. The hand held scraper of claim 10, wherein said upper surface comprises two or more sections angularly oriented with respect to one another. 12. The hand held scraper of claim 10, wherein said upper surface comprises three or more sections angularly oriented with respect to one another. 13. The hand held scraper of claim 10, wherein said cantilever abrader comprises an abrasive protrusion positioned on a section of said upper surface of said cantilever abrader, wherein said section is substantially perpendicular to said scraping edge. 14. The hand held scraper of claim 10, further comprising two substantially rigid members that constrain a vertical range of motion of said cantilever abraders, wherein said plurality of cantilever abraders are positioned adjacent to and between said two substantially rigid members. 15. The hand held scraper of claim 10, wherein said body is configured as a two tiered structure comprising an upper frame and a lower frame attached to said upper frame, wherein said handle is attached to said upper frame and wherein said first end is hinged to a surface of said lower frame. 16. The hand held scraper of claim 15, further comprising a brush mounted to said upper frame, wherein said brush comprises a plurality of bristles that are independently moveable relative to one another. 17. The hand held scraper of claim 16, wherein said handle has a domed shape configuration attached to an inclined elongated wrist rest flange. 18. The hand held scraper of claim 16, further comprising a third frame removably attached to said lower frame, and wherein a plurality of teeth are positioned on a lower surface of said third frame. 19. The hand held scraper of claim 10, further comprising a shield for deflecting said substance, wherein said shield is positioned above said plurality of cantilever abraders and wherein a lower edge of said shield further constrains said vertical range of motion of said cantilever abraders. 20. The hand held scraper of claim 10, comprising a liquid dispenser capable of dispensing a cleaning fluid, wherein said liquid dispenser is positioned within a cavity of said handle.
