     BACKGROUND OF THE INVENTION 
     A. Field of the Invention 
     The present invention relates to the field of hunting arrows, more specifically, a hunting arrow in which the head has an open boring head. 
     B. Discussion of the Prior Art 
     As a preliminary note, it should be stated that there is an ample amount of prior art that deals with hunting arrows, generally. As will be discussed immediately below, no prior art discloses a tip of a hunting arrow that includes a hole about the center, which cuts a hole into the skin and flesh of game in order to enable unimpeded blood loss therefrom; wherein the hole is formed from a plurality of points that are notched into the front of the arrowhead such that at least a portion of the arrow shaft is hollow; wherein the hole of the tip of the arrow extends rearwardly for at least a portion of the arrow shaft; wherein the arrowhead may include a plurality of external blades that extend radially from the exterior surface of the arrow shaft; wherein a ballistic tip is included and covers the arrowhead during flight to account for aerodynamics, and which is cut away upon impact with the target. 
     The Delmonte et al. Patent (U.S. Pat. No. 5,044,640) discloses an arrow broadhead tip having a plurality of razor sharp blades to cleanly cut a hole into an animal proving means for the animal to profusely bleed to death unimpeded by loos skin or hide closing the hole. However, the arrow broadhead tip does not have an open design such that the center of the arrow tip is an open hole that extends rearwardly through at least a portion of the arrow shaft such that upon impact with game, a hole is bored through the skin and flesh in order to maximize blood loss therefrom. 
     The Sutherland et al. Patent (U.S. Pat. No. 6,669,585) discloses a hunting arrow having a hollow cylindrical shaft. However, the hunting arrow does not include an arrow head in which the tip is a hollowed hole that extends rearwardly through at least a portion of the shaft and which forms a hole in the flesh of game, which unimpedes blood loss therefrom. 
     The Repinski et al. Patent (U.S. Pat. No. 4,212,463) discloses a hunting arrow designed to obtain the most bleed-out possible comprising a hollow shaft. However, the hunting arrow features an arrow tip that is not a hole formed about the center of said tip and which cuts a hole into the skin and flesh of game thereby unimpeding blood loss. 
     The Johnson Patent (U.S. Pat. No. 3,993,311) discloses a hunting arrow that will cause massive bleed in wounded game having a hollow shaft. However, the hunting arrow does not have an arrow tip with an open holed center that cuts a hole through both the skin and game of game upon impact, which produces unimpeded blood loss therefrom. 
     The Watkins et al. Patent (U.S. Pat. No. 6,863,630) discloses a hunting arrow having a cutting ring to promote bleeding of hunted game. Again, the cutting ring of the hunting arrow is not an arrow tip having a hole thereon, which extends rearwardly through at least a portion of the arrow shaft and upon impact shall bore a hole through the skin and flesh of game thereby producing unimpeded blood loss. 
     The Graham Patent (U.S. Pat. No. Des. 384,126) illustrates a design for a broadhead, which does not resemble an open arrow tip. 
     The Johnson Patent (U.S. Pat. No. Des. 342,303) illustrates an ornamental design for a broadhead. Again, the tip of the broadhead includes lateral members that do not form a truly open hole across the center of the tip of the arrow head. 
     While the above-described devices fulfill their respective and particular objects and requirements, they do not describe a tip of a hunting arrow that includes a hole about the center, which cuts a hole into the skin and flesh of game in order to enable unimpeded blood loss therefrom; wherein the hole is formed from a plurality of points that are notched into the shaft of the arrowhead such that at least a portion of the arrow shaft is hollow; wherein the hole of the tip of the arrow extends rearwardly for at least a portion of the arrow shaft; wherein the arrowhead may include a plurality of external blades that extend radially from the exterior surface of the arrow shaft; wherein a ballistic tip is included and covers the arrowhead during flight to account for aerodynamics, and which breaks away upon impact with the target. In this regard, the hunting arrow having a hole boring head departs from the conventional concepts and designs of the prior art. 
     SUMMARY OF THE INVENTION 
     The hunting arrow having a hole boring head includes an arrow shaft that attaches an arrowhead comprised of points that are notched into the head such that the arrowhead and at least a portion of the arrow shaft have an open hole in the center in order to cut a hole through the skin and flesh of game for unimpeded blood loss therefrom. The points constructed of notches are concentrically arranged, and require at lease a portion of the arrow shaft to be hollowed such that the open hole extends rearwardly with respect to the shaft. The hunting arrow may include a plurality of external blades that extend radially from the exterior surface of the arrowhead, and may be centered about each of the points. A ballistic tip is included and covers the arrowhead during flight to account fox aerodynamics, and which is cut through itself and breaks apart upon impact with the target, after which the arrowhead cuts through said target. 
     An object of the invention is to provide a tip of a hunting arrow that is formed of points notched into the arrowhead such that a centrally aligned hole is formed and which cuts a hole through the skin and flesh of game, which produces an inlet hole, a core hole, and an exit hole that does not impede blood loss therefrom. 
     A further object of the invention is to provide an arrowhead having a hole boring head therein, which is attached to the arrow shaft, and which forms the points via the notches on the arrowhead. 
     An even further object of the invention is to have a hole boring head that extends rearwardly through the arrowhead and at least a portion of the arrow shaft. 
     A further object of the invention is to provide external blades that extend radially from the exterior of the arrow shaft. 
     An even further object of the invention is to provide external blades that align with the points forming the arrowhead. 
     A further object of the invention is to provide a nock that attaches to the aft end of the arrow shaft, and which is detachably engaged therein. 
     Another object of the invention is to include a ballistic tip that attaches over the arrowhead, and which is cut through and breaks apart upon impact with the target, and thereafter enables the arrowhead to cut through said target. 
     These together with additional objects, features and advantages of the hunting arrow having a hole boring head will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the hunting arrow having a hole boring head when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE EMBODIMENT 
     The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. 
     Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in  FIGS. 1-6B . A hunting arrow having a hole boring head  100  (hereinafter invention) includes an arrow shaft  101  defining an arrowhead  102  at a forward most end of the arrow shaft  101 . Located at the arrowhead  102  are a plurality of points  103  formed via notches  104 , which are cut into the arrowhead  102 :. Both the notches  104  and the points  103  are concentrically aligned about a hollowed arrow shaft  101  such that a boring hole  105  (hereinafter hole) is formed therein. It shall be noted that the formation of the boring hole  105  is the genesis behind the invention  100  in that upon impact of the arrowhead  102  into game  130 , a disc-shaped plug  130 A is cut from the skin and flesh of the game  130 , and an inlet hole  131 , an outlet hole  132 , and a core hole  133  results into the skin and flesh of the game  130 , which cannot close up and thereby assists in unimpeded blood loss  140  (see  FIG. 6A ). It shall be noted that the term corn hole  133  is being used to indicate a channel spanning between the inlet hole  131  and the outlet hole  132 . 
     It shall be noted that the force of impact of the arrowhead  102  into the game  130  shall simultaneously cut out the disc-shaped plug  130 A, which travels into the arrow shaft  101  and exits from the game  130  within the invention  100 . It shall be noted that the invention  100  forms the inlet hole  131 , the outlet hole  132 , and the core hole  133 , which collectively are incapable of sealing shut. Moreover, the invention  100  ideally travels entirely through the game  130 , and from which blood  140  exits. 
     It shall be noted that the arrow shaft  101  does not have to be hollowed along a length  101 A. Rather, the arrow shaft  101  shall be hollow for at least a portion of the arrow shaft  101  in order to accommodate the disc-shaped plug  130 A as well as insertion of the arrowhead  102 . Please note that the arrow shaft  101  is likely hollowed through the entire length  101 A, in order to promote proper functionality of the invention  100  during flight, and that less than the entire length  101 A is being hereby asserted as a possible embodiment of use of the invention  100 . 
     It shall be further noted that both the points  103  and notches  104  are concentrically arranged around the arrow shaft  101 . Moreover, the points  103  and notches  104  shall have a sharpened edge that further aids in penetration of the arrowhead  102  into the skin and flesh of game  130 . 
     In referring to  FIGS. 4A-4D , the invention  100  may employ at least two points  103 .  FIGS. 4A-4D  depict multiple numbers of points  103  ranging from two to six. However, it shall be noted that other number of points  103  and notches  104  may be employed so long as the arrangement is concentrically aligned about the arrow shaft  101 . 
     It shall be further noted that the term “concentrically aligned” is being used to indicate that the points  103  and the respective notches  104  are symmetrically offset from one another around the arrow shaft  101 . The use of the term “concentrically aligned” is important in order for the invention  100  to operate effectively, aerodynamically speaking. 
     Referring to  FIGS. 5A-5D , the invention  100  may include external blades  106  that extend radially from an exterior surface  101 B of the arrow shaft  101 . Moreover, the external blades  106  align with and equal to the number of points  103  of the respective embodiment of the invention  100 . It shall be noted that the alignment of the external blades  106  is also important to the aerodynamic function of the invention  100 . The external blades  106  include a sharpened edge  106 A, which are angled back towards the arrow shaft  101 , and which produces a V-shape or angle to catch on brush in the event that the arrowhead  102  travels through the game  130 , but the entire invention  100  does not pass completely through the game  130 . In said event, the sharpened edge  106 A of the external blades  106  shall engage on brush in order to pull the invention  100  entirely through said game  130  for the purpose of securing unimpeded blood flow from both the inlet hole  131  and the outlet hole  132 . 
     It shall be noted that the invention  100  includes fletchings  107  that are arranged at the rear end of the arrow shaft  101 , and are well known in the prior art. Moreover, the invention  100  includes a nock  108  that is detachably engaged with respect to the rear shaft hole  101 C. The nock  108  is slideably engaged within the rear shaft hole  101 C, and may include a magnet  108 A for temporary attachment thereto. The magnet  108 A shall work in conjunction with the arrow shaft  101 , which is constructed of a magnetic or ferrous material in order to accommodate magnetic attraction there with. The nock  108  may include a shoulder  108 B to limit the amount of travel into the rear shaft hole  101 C. 
     It should be noted that the nock  108  will have a snug fit with the arrow shaft  101 , and may not require magnetic attraction there between. Moreover, the nock  108  would simply disconnect from the arrow shaft  101  upon impact with the game  130  during which air pressure shall increase due to the disc-shaped plug  130 A traveling inside of the arrow shaft  101 , and which would expel the nock  108  from the arrow shaft  101 . 
     The invention  100  may include a ballistic tip  109  that attaches onto the invention  100 . Moreover, the ballistic tip  109  fits over the arrowhead  102 , and upon impact with the game  130  shall be cut through itself and break apart. The ballistic tip  109  shall be construction of a material that is relatively weak in comparison with the material comprising the arrowhead  102 . The ballistic tip  109  is designed to enable aerodynamic flow across the invention  100  during flight, and upon impact with the game  130 , the ballistic tip  109  shall cut through itself and break apart. 
     The ballistic tip  109  includes a cone portion  109 A seated onto a shoulder  109 B that has a length  109 C greater than the arrowhead  102 . Referring to  FIG. 6B , the ballistic tip  109  may include slots  109 D, which accommodate the external blades  106  of the embodiments of  FIGS. 5A-5D . The slots  109 D may be provided on the shoulder  109 B portion of the ballistic tip  109 . The slots  109 D shall be arranged and aligned according to the spacing and placement of the external blades  106 . Moreover, the slots  109 D improve the ability of the ballistic tip  109  to cut through itself and break apart from the arrowhead  102  during impact with the game  130 . 
     With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention  100 , to include variations in size, materials, shape, form, function, and the 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 invention  100 . 
     It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
