     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 6 thereof, a new knife and tacking device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. More specifically, it will be noted that the knife and tacking device 10 comprises a tacking means 12 for driving an impact driven fastener Into a surface in response to an impact of the tacking means against such surface. A cutting blade means 14 is secured to the tacking means 12 for cutting objects in response to a manual manipulation of the tacking means. 
     As best illustrated in FIGS. 1, 2, and 4, it can be shown that the tacking means 12 according to the present invention 10 preferably comprises an elongated upper channel member 16, with an elongated lower channel member 18 pivotally mounted to the elongated upper channel member at a rearward end 20 thereof. The elongated lower channel member 18 is positioned so as to be pivotally received within the elongated upper channel member 16 and includes a dispensing means 22 mounted within the elongated lower channel member 18 for dispensing an impact driven fastener in response to a pivoting movement of the elongated lower channel member into the elongated upper channel member. By this structure, an impacting of the elongated lower channel member 18 against a surface will drive the lower channel member into the upper channel member 16 and effect dispensing of an impact fastener, such as a tack or a staple, from the dispensing means 22. A handle cover 24 extends about a rearward end 20 of the elongated upper channel member 16 and the lower channel member 18 and provides a gripping surface operable to preclude slipping of the device 10 during manual manipulation thereof. Further, the handle cover affords an unillustrated compartment for storage of staples therein. Such storage and dispensing is done in a conventional manner with a spring and associated tab for forcing the staples to an opening of the dispensing means. Further, a locking tab 25, shown in FIG. 4, is included for permitting access to the compartment of the handle. 
     Referring now to FIG. 3 with concurrent reference to Figures previously discussed, it can be shown that the cutting blade means 14 according to the present invention 10 is mounted to the elongated upper channel member 16 so as to project beyond a forward end 26 thereof. To this end, the cutting blade means 14 preferably comprises a planer mounting plate 28 secured to an upper surface of the elongated upper channel member 16 by at least one fastener 30, such as a rivet, threaded fastener, or the like. The planer mounting plate 28 integrally continues into a planar blade plate 32 extending beyond the forward end 26 of the upper channel member 16. The planar blade plate 32 is shaped so as to define an outer arcuate edge 34 continuing through an arc of approximately greater than ninety degrees such that the planar blade plate 32 projects at least partially laterally of the upper channel member 16 substantially as shown in FIG. 3. The planar blade plate 32 is further shaped so as to define an inner arcuate edge 36 extending from an opposed side of the planar mounting plate 28 relative to a side of the planar mounting plate 28 from which the outer arcuate edge 34 continues. The inner arcuate edge 36 similarly extends through an arc of approximately ninety degrees to couple with the outer arcuate edge 34 to define a piercing tip 38 operable to piercingly engage a surface. Either of the edges 34 or 36 can be sharpened to impart a cutting ability to the cutting blade means 14. However, the outer edge 34 is preferably blunt, with only the inner arcuate edge 36 and the piercing tip 38 being sharpened, By this structure, the piercing tip 38 cooperates with the sharpened inner arcuate edge 36 to effect cutting of an object such as sealing paper or the like during a roofing procedure. 
     In use, the knife and tacking device 10 according to the present invention can be utilized to both cut objects, as well as to secure objects through the dispensing of an impact driven fastener thereinto. Additionally, and as shown in FIG. 5, the tacking means 12 can be secured between adjacent underlayment boards 40 of an incomplete roof structure by a positioning of the cutting blade means 14 therebetween. A roll of roofing material 42 can then be positioned into abutting engagement with the tacking means 12 to preclude a sliding of the roll of roofing material 42 from the associated incomplete roof structure. Further, the cutting blade means 14 can also be utilized to piercingly engage an underlayment board 40 to suspend or secure the tacking means 12 to the incomplete roof structure. Thus, a synergistic effect between the cutting blade means 14 and the tacking means 12 results from the specific mounting of the cutting blade means 14 relative thereto. 
     As an option, the handle cover 24 is equipped with a tab 50 extending outwardly therefrom. As shown in FIG. 3, the tab has an aperture formed therein for coupling the present invention to the user or for storage purposes. Preferably, the is integrally coupled to an associated plate situated within an entire length of the handle. This affords a more reliable hanging means. Further, as shown in FIG. 4, the tab extends beyond the locking tab for preventing the inadvertent manipulation and removal of the staples. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
