ABSTRACT:
A broadhead assembly includes a substantially planar metal blade that defines a plane of symmetry relative to the blade. The blade includes first and second sharp edges which are symmetric relative to the plane of symmetry. The first and second sharp edges nearing each other and defining a tip area therebetween and defining a cutting bevel of between 17 and 30 degrees. The tip area is characterized by third and fourth sharp edges which are symmetric relative to the plane of symmetry. The third edge is adjacent to the first edge at a first inflection point and adjacent to the fourth edge at the tip area. The fourth edge is adjacent to the third edge at the tip area and the second edge at a second inflection point, wherein the angle formed between the first inflection point, the tip area, and the second inflection point is between 40 and 65 degrees. The first edge and the second edge and the third edge and the fourth edge each have a length wherein each of the first and second sharp edges extend at least an inch in length. The length of the third edge is between ⅓ and 1/7 of the length of the first edge and the length of the fourth edge is between ⅓ and 1/7 of the length of the second edge. Each of the third edge and the fourth edge define a penetrating bevel of between 20 and 35 degrees.
