Patent ID: 7597637

Claim:
A broadhead assembly comprising a blade, characterized in that the blade is metal; the blade characterized as substantially planar, the blade defining a plane of symmetry relative to the blade; the blade comprising first and second sharp edges, wherein the first edge and the second edge are straight, the first edge and second edge defining a first angle, the first edge and second edge, if extended, having lines of intersection at a first intersection point; the first and second sharp edges symmetric relative to the plane of symmetry; the first and second sharp edges nearing each other and defining a tip area therebetween; each of the first and second sharp edges defining a cutting bevel of between 17 and 30 degrees; the tip area characterized by third and fourth sharp edges, the third and fourth sharp edges symmetric relative to the plane of symmetry; the third edge adjacent to the first edge at a first inflection point and adjacent to the fourth edge at the tip area; the fourth edge adjacent to the third edge at a second intersection point and adjacent to the second edge at a second inflection point; wherein a second angle defined by the first inflection point, the second intersection point, and the second inflection point is between 40 and 65 degrees; wherein the second angle is greater than the first angle; wherein the second intersection point lying between the first intersection point and the blade; the first edge and the second edge and the third edge and the fourth edge each having a length; each of the first and second sharp edges extending at least an inch in length; the length of the third edge characterized as between ⅓ and 1/7 of the length of the first edge; the length of the fourth edge characterized as between ⅓ and 1/7 of the length of the second edge; and each of the third edge and the fourth edge defining a penetrating bevel of between 20 and 35 degrees.
