1. Field of the Invention
The present invention is for an arrowhead, and more particularly is for an arrowhead having refined cutting blades.
2. Description of the Prior Art
Prior art arrowheads have included multiple blades which serve to enter the mass which an arrowhead impinges. Often the blade edges have had no modification or would utilize simple opposed wide-angle bevel cuts to effect a rudimentary cutting, ripping or tearing edge which forced target surfaces apart by brute force action. The lack of good slicing, piercing and parting qualities of the blades resulted in much of the force of the projectile arrow being expended in just breaking through the target surface, thereby leaving less potential energy for deep penetration. As a consequence, an effective shoot, that is, a shoot making a sufficiently deep wound entry to achieve a successful result, was difficult to attain. With the popularity of bow hunting, hunters have expanded the hunt from commonly hunted animals to larger and more challenging prey, such prey having thicker and tougher hides or skin. Against such prey, the effectiveness of prior art arrowheads is even less. Clearly, what is needed is an arrowhead offering adequate cutting qualities which would allow easier entry and deep penetration of a hunter's arrow into the target or wildlife game.
The general purpose of the present invention is to provide an arrowhead having blades with improved cutting edges.
According to the present invention, there is provided an arrowhead including a plurality of blades each having a cutting edge which has a narrow cutting angle produced by opposing broad finely ground or honed surfaces which extend inwardly a considerable distance from the outer periphery of the cutting edge toward the center of the arrowhead to effect a narrow profile sharp cutting edge. The blades are interchangeable and replaceable by the user as desired.
One significant aspect and feature of the present invention is an arrowhead which can deeply penetrate a target or wildlife game.
Another significant aspect and feature of the present invention is an arrowhead having blades which are finely ground, honed or otherwise fashioned to provide for a narrow angle cutting edge along the length of each blade.
Still another significant aspect and feature of the present invention is an arrowhead having finely fashioned blades which are cutting instruments of improved effectiveness and efficiency.
Yet another significant aspect and feature of the present invention is an arrowhead having blades which penetrate using a slicing action.
A further significant aspect and feature of the present invention is an arrowhead which slices a target or wildlife game surface instead of tearing or ripping such target or wildlife game surface, thereby expending minimal energy for initial entry and allowing remaining energy to be utilized for deep penetration into the target or wildlife game.
Having thus enumerated significant aspects and features of the present invention, it is the principal object of the present invention to provide an arrowhead having improved sharpened and profiled blades for easy entry into a target or wildlife game.
Other objects of the present invention and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, in which like reference characters designate like parts throughout the figures thereof and wherein:
The chisel tip 16 of the arrowhead 10, the present invention, first encounters the target or wildlife game to initially create a small puncture to allow initial entry of the arrowhead 10. Subsequently, the blades 20a-20n, having cutting edges 22 formed by the opposing broad ground surfaces 44a and 44b, at an angle in a range of 5°-25°, and such as 20°, part the target or wildlife game by a slicing action as opposed to ripping or by brute force entry, such as by prior art blades 50. Such slicing action expends minimal energy for entry, thereby conserving remaining energy to be spent for carriage of the arrowhead past the initial parted surfaces and deep into the target or wildlife game.
Various modifications can be made to the present invention without departing from the apparent scope hereof.
