The invention claimed is: 1. A driving tool for propelling fasteners into a workpiece, comprising: a housing; a power source located in said housing; a nosepiece connected to a lower end of said power source; a magazine associated with said housing and constructed and arranged for storing and seque
The invention claimed is: 1. A driving tool for propelling fasteners into a workpiece, comprising: a housing; a power source located in said housing; a nosepiece connected to a lower end of said power source; a magazine associated with said housing and constructed and arranged for storing and sequentially feeding a plurality of fasteners to said nosepiece; and a workpiece contact element associated with said nosepiece and comprising: a nose section having a front wall, a rear wall, and a pair of sidewalls, wherein the rear wall is closer to the magazine than the front wall, and at least one rear tooth extending from the rear wall obliquely to a longitudinal axis of the nosepiece in a direction away from the front wall, and being constructed and arranged for gripping the workpiece to enable the tool to actuate when said magazine is arranged generally parallel to the workpiece. 2. The tool of claim 1, wherein the nose section is slidable along the longitudinal axis of the nosepiece for surrounding and slidingly accommodating said nosepiece, and said at least one rear tooth is located between said magazine and said nosepiece. 3. The tool of claim 2, wherein said at least one rear tooth extends from the rear wall at an oblique angle to an edge of said magazine, said edge being adapted to be in direct surface contact with the workpiece. 4. The tool of claim 2, wherein said at least one rear tooth is slanted at approximately 10° from the longitudinal axis of the nosepiece and extends distally from said nose section toward said magazine. 5. The tool of claim 1, wherein the at least one rear tooth comprises a pair of rear teeth each having a pointed end distally located from said nose section and constructed and arranged for engaging the workpiece. 6. The tool of claim 5, wherein said nose section has a generally rectangular cross-section and includes at least one prong extending from the front wall to be located opposite from said pair of rear teeth, and spaced from said teeth to be further away from said magazine than said teeth. 7. The tool of claim 6, wherein said nose section further includes a pair of side teeth, each extending from one of the sidewalls and being located between said prong and one of said rear teeth. 8. The tool of claim 7, wherein each of said side teeth extends obliquely from the respective sidewall in a direction away from the other sidewall. 9. A workpiece contact element for use with a driving tool for propelling fasteners into a workpiece, the tool including a housing, a power source located in the housing, a nosepiece associated with a lower end of the power source, and a magazine associated with the housing and configured for storing and sequentially feeding a plurality of fasteners to the nosepiece, the workpiece contact element comprising: a nose section constructed and arranged for surrounding the nosepiece, said nose section having a front wall, a rear wall adapted to be positioned closer to the magazine than the front wall, and a pair of sidewalls; and at least one rear tooth extending obliquely from said rear wall in a direction away from the front wall, adapted to be located between the magazine and the nosepiece, and constructed and arranged for engaging the workpiece when the magazine is generally parallel to the workpiece. 10. The workpiece contact element of claim 9, wherein said at least one rear tooth is slanted at approximately 10° from a longitudinal axis of the nosepiece and towards the magazine. 11. The workpiece contact element of claim 9, wherein the at least one rear tooth comprises a pair of rear teeth. 12. The workpiece contact element of claim 11, wherein said rear wall has a gap, and said rear teeth are located on opposite sides of said gap. 13. The workpiece contact element of claim 9, wherein said nose section has a generally rectangular cross-section taken transversely to a longitudinal axis of the nosepiece, and includes a prong extending from the front wall to be located on an opposite side of said nose section from said at least one rear tooth, and being spaced from said at least one rear tooth to be further from the magazine than said at least one rear tooth. 14. The workpiece contact element of claim 13, wherein the at least one rear tooth extends farther distally from said nose section than said prong. 15. The workpiece contact element of claim 14, wherein said prong extends distally along the longitudinal axis of the nosepiece. 16. The workpiece contact element of claim 13, wherein said nose section further includes a pair of oppositely located side teeth, each formed between said prong and said at least one rear tooth, wherein said teeth are slanted relative to the longitudinal axis and diverge away from each other as said side teeth project farther from the nosepiece.
