Abstract

An arrowhead includes a body having a longitudinal axis, a pair of moveable first blades coupled to the body, a second blade having a tip and a rear portion opposite the tip, and a second fastener that engages the rear portion and fixedly couples the second blade to the body.

Claims

1. An arrowhead comprising:

a body having a longitudinal axis;

a pair of moveable first blades coupled to the body;

a second blade having a tip and a rear portion opposite the tip; and

a second fastener that engages the rear portion and fixedly couples the second blade to the body.

2. The arrowhead of claim 1, wherein the rear portion comprises an extending portion having a tab that defines a first recess.

3. The arrowhead of claim 2, wherein the second fastener comprises a second recess configured to receive the tab.

4. The arrowhead of claim 1, wherein the second fastener is configured to be rotated about the longitudinal axis.

5. The arrowhead of claim 4, wherein the second fastener is a generally cylindrical member that comprises the second recess.

6. The arrowhead of claim 4, wherein rotating the second fastener tends to pull the second blade toward the body in a direction along the longitudinal axis.

7. The arrowhead of claim 1, wherein the second fastener comprises a plurality of generally cylindrical members.

8. The arrowhead of claim 1, wherein the second blade is a cut-on-contact blade.

9. The arrowhead of claim 1, wherein the pair of moveable blades are configured to be in a retracted position during flight and extend to an extended position upon impact with a target.

10. The arrowhead of claim 1, further comprising:

a pair of first fasteners that are positioned offset relative to the longitudinal axis and rotatably couple the moveable blades to the body.

11. The arrowhead of claim 10, wherein the body is configured to receive a third blade that is interchangeable with the pair of moveable first blades and is fixably coupleable to the body using the pair of first fasteners.

12. The arrowhead of claim 1, wherein the body is configured to receive a third blade that is interchangeable with the second blade and differs from the first blade in at least one of a size and a weight.

13. The arrowhead of claim 1, wherein the second blade includes a cut-out portion extending from a cutting edge.

14. A body for an arrowhead, comprising:

a body portion;

first means for fixedly securing a first fixed blade to the body portion; and

second means for interchangeably fastening a second fixed blade to the body portion in a first configuration and rotatably coupling a pair of expandable blades to the body portion in a second configuration.

15. The body of claim 14, wherein the body has a longitudinal axis, and the second means engage the body in a position offset from the longitudinal axis.

16. The body of claim 14, wherein the first means comprises a generally cylindrical member.

17. The body of claim 14, wherein the first means comprises a plurality of generally cylindrical members.

18. The body of claim 14, wherein the first fixed blade is a cut-on-contact blade.

19. The body of claim 14, wherein at least one of the first fixed blade and the second fixed blade includes a cutting edge having at least one cut-out portion.

20. A method of configuring an arrowhead comprising:

providing a body portion, a pair of first fasteners, and a second fastener;

coupling a pair of moveable blades to the body portion with the pair of first fasteners;

coupling a first fixed blade to the body portion with the second fasteners;

removing the pair of moveable blades from the body portion; and

coupling a second fixed blade to the body portion.

21. The method of claim 20, wherein coupling the second fixed blade to the body portion comprises securing the second fixed blade between the first fixed blade and the body portion.

22. The method of claim 21, further comprising coupling the first fixed blade to the body portion with the pair of first fasteners.
