Abstract

An arrowhead includes a conical forward region (16), a pair of chisel regions (18) on opposing sides of the arrowhead (10), and a pair of wedge regions (20) on opposing sides of the arrowhead (10), wherein the wedge regions (20) are positioned adjacent and between the chisel regions (18) around the circumference of the arrowhead (10). The conical forward region (16) assists in stabilizing the flight of the arrow and in directing the arrowhead (10) into a target animal. The chisel regions (18) and wedge regions (20) enhance the arrowhead'"'"'s (10) ability to pass through bone, cartilage, hide, and other difficult to penetrate materials. The chisel regions (18) and wedge regions (20) are distinct from the conical forward region (16) in that the conical forward region (16) is cone shaped around its circumference, while the chisel regions (18) and wedge regions (20) are planar in character. The wedge regions (20) are composed of a first angular region ( 26) and a second angular region (28), where the first angular region (26) has a smaller total angle than the second angular region (28). Thus, the first angular region (26) and second angular region operate in conjunction to "wedge-open" or separate bone, cartilage, or other dense matter.

Claims

1. A point for an arrowhead, comprising:

a body having a first and a second end, said second end for penetrating a game animal;

a conical region positioned at said second end of said body, said conical region having a first end which terminates at a first axial location on said body, and a second end which terminates in a conical point at said second end of said body;

first and second chisel regions positioned on opposite sides of said body, said first and second chisel regions each beginning on said body at said first axial location on said body and terminating at a second axial location on said body; and

first and second wedge regions positioned on opposite sides of said body and radially between said first and second chisel regions, said first and second wedge regions each being comprised of first and second angular regions wherein said first angular region begins on said body at said first axial location on said body and terminates at a third axial location on said body, and said second angular region begins on said body at said third axial location on said body and terminates at a fourth axial location on said body, and wherein said first angular region forms a first total angle with respect to a longitudinal axis of said body and said second angular region forms a second total angle with respect to said longitudinal axis of said body and said first total angle is smaller than said second total angle.

3. The point of claim 1 wherein said conical region has an axial dimension of 0.05-0.5 inches.

4. The point of claim 1 wherein said first total angle ranges between 0°

-30°

.

5. The point of claim 1 wherein said second total angle ranges between 10°

-60°

.

6. The point of claim 1 wherein said first total angle ranges between 0°

-10° and

said second total angle ranges between 30°

-60°

.

7. The point of claim 1 wherein said fourth axial location on said body is approximately the same as said second axial location.

8. The point of claim 1 wherein said fourth axial location on said body is relatively closer to said first end of said body than said second axial location.

9. The point of claim 1 wherein said second axial location on said body is relatively closer to said first end of said body than said fourth axial location.

10. The point of claim 1 wherein said first and second chisel regions form a fourth total angle with respect to said longitudinal axis of said body which ranges between 5°

and 35°

.

2. The point of claim I wherein said conical region has a third total angle of 5°

-35°

.
