What is claimed is: 1. A one piece work contact tip for mounting to a U-shape drive probe of a fastening tool having a driver blade for driving a fastener into a workpiece, said work contact tip comprising: a body including ends, a front side, a rear side opposite said front side, a work contact surface, and a trailing surface opposite said work contact surface; a pair of wins connected to said front side of said body at said ends; said pair of wings having resilient contact surfaces for contacting said workpiece, said wings forming a channel for said fastener and for visually locating the position where said fastener will be driven into said workpiece; a recess located in said trailing surface of said body for retaining said drive probe, and thereby mounting said work contact tip to said drive probe, said recess being generally U-shaped to complement and receive the U-shape of said drive probe. 2. A work contact tip according to claim 1, further comprising a ledge in said recess to retain said drive probe in said recess. 3. A fastener driving tool according to claim 2 wherein said ledge includes a ramp for allowing said drive probe to slide along said ramp into said recess and wherein ends of the recess adjacent said trailing surface include chamfers to allow said work contact tip to pivot in a side-to-side manner with respect to said drive probe so that said tool can be used in tight spaces, such as corners, where said tool cannot be oriented completely vertically. 4. A work contact tip according to claim 1, wherein said recess has chamfered ends that allow said work contact tip to pivot during operation with respect to said drive probe. 5. A work contact tip according to claim 1, wherein said channel of said work contact tip is configured to receive a nose of said fastening tool. 6. A work contact tip according to claim 1, wherein at least one of said wings includes an index for the position where said fastener will be driven into said workpiece. 7. A work contact tip according to claim 1, wherein at least lower portions of said wings are tapered toward said contact surfaces. 8. A work contact tip according to claim 1, further comprising means for connecting said pair of wings to said drive probe. 9. A fastener driving tool according to claim 1 wherein said body has a thickness that is between 25% and about 50% of a total length of said work contact tip and width that is essentially the entire width of said work contact tip. 10. A fastener driving tool according to claim 1 wherein said wings include contact surfaces for contacting said workpiece, trailing surfaces facing generally opposite said contact surfaces, rear ends connected to said body, front ends opposite said rear ends, outside surfaces and inside surfaces, and wherein said wings have a predetermined length between said front ends and a position where a fastener will be driven selected so that said wing ends can be pushed against a surface, and a fastener will be driven close to the surface. 11. A fastener driving tool according to claim 10 wherein said length of said wings is between about 50% and about 75% of a total length of the work contact tip, a length between said wing front ends and said fastener position is between about 20% and about 40% of the total length of the work contact tip and between about 25% and about 75% of the length of the wings. 12. A fastener driving tool according to claim 1 wherein each wing has a thickness of between about 15% and about 35% of a total width of the work contact tip, so that the channel has a width of between about 30% and about 70%, of the total width of the work contact tip. 13. A fastener driving tool according to claim 1 wherein the work contact tip 10 has a width of between about 쩍 inch and about 1 inch, a length of between about 0.4 inch and about 1 inch, and a height of between about 쩌 inch and about 쩐 inch, wherein said body has a thickness of between about 0.1 inch and about 0.35 inch, wherein said wings have a length of between about 쩌 inch and about 쩍 inch, and a thickness of between about 0.1 inch and about 0.3 inch, and wherein a length between the wing front ends and a desired fastener position is between about 0.05 inch and about 0.35 inch. 14. A fastener driving tool according to claim 1 wherein said work contact tip is made from a resilient material such that said wings can spread apart and away from said channel whereby outside portions of said body rear side pinch together so that the drive probe is tight held within said recess, substantially preventing said work contact tip from becoming disengaged with drive probe. 15. In combination, a drive probe of a fastening tool having a driver blade for driving a pin into a workpiece, and a work contact tip mounted to said drive probe, wherein said work contact tip comprises: a generally horseshoe shaped member having a body including ends, a front side, a rear side opposite said front side, a work contact surface, and a trailing surface opposite said work contact surface; a pair of wings connected to said front side of said body at said ends; said pair of wings having resilient contact surfaces for contacting said workpiece, said wings forming a channel for said pin and for visually locating the position where said pin will be driven into said workpiece, while allowing for visually locating the position where said pin will be driven into said workpiece, and wherein said drive probe is oriented perpendicular to the work surface. 16. A combination according to claim 9, wherein said channel faces in a forward direction relative to said tool. 17. A fastening tool comprising: a driver blade for driving a fastener into a workpiece; a power source for driving said driver blade; a housing enclosing said driver blade, said housing including a nosepiece for accepting said fastener and for axially guiding said driver blade in a driving direction toward impact with said fastener; a wire drive probe extending in the driving direction from said housing to a driving end; and a resilient work contact tip mounted to said driving end of said drive probe, said work contact tip having a body body including ends, a front side, a rear side opposite said front side, a work contact surface, and a trailing surface opposite said work contact surface; a pair of wings extending from said front side of said body at said ends; said pair of wings having resilient contact surfaces for contacting said workpiece, said wings forming a channel for said fastener while allowing for visually locating the position where said fastener will be driven into said workpiece. 18. A fastener driving tool according to claim 17, wherein said wings have ends and a predetermined length selected for positioning of said fastener at a predetermined distance from said ends of said wings. 19. A fastener driving tool according to claim 17, wherein said work contact tip further comprises a recess in said trailing surface for retaining said drive probe, and thereby mounting said work contact tip to said drive probe, said recess being generally U-shaped to complement and receive the U-shape of drive probe.
