Abstract

A steering element for a blade which is preferably mounted with respect to or part of an arrowhead or broadhead. During flight, a leading surface of the steering element contacts with airflow. One or more force components act in a direction generally perpendicular to a flat surface of the blade, to impart rotation or spin of a body of the arrowhead about a longitudinal axis of the arrowhead.

Claims

1. An arrowhead comprising:

at least two blades attached with respect to a body of the arrowhead, each of said blades having a flat surface on at least one face of one of said blade and an insert mounted within a cutout of said blade, and a steering element extending outward from said flat surface.

2. An arrowhead according to claim 1, wherein said steering element has a leading surface, and a distance between said leading surface and said flat surface of said blade increases in a direction from a front of said leading surface to a rear of said leading surface.

3. An arrowhead according to claim 2, wherein said leading surface is flat.

4. An arrowhead according to claim 2, wherein said leading surface is curved.

5. An arrowhead according to claim 2, wherein at least a portion of said leading surface is concave.

6. An arrowhead according to claim 1, wherein said steering element is integrated with said blade.

7. An arrowhead according to claim 1, wherein said steering element is connected to said blade.

8. An arrowhead according to claim 1, wherein said flat surface is planar.

9. An arrowhead according to claim 1, wherein each said blade is removably attached to said body.

10. An arrowhead according to claim 1, wherein each said blade is pivotably mounted with respect to said body.

11. A blade for an arrowhead, the blade comprising:

said blade having a flat surface on at least one face of one of said blade and an insert mounted within a cutout of said blade, and a steering element extending outward from said flat surface.

12. A blade according to claim 11, wherein said steering element has a leading surface, and a distance between said leading surface and said flat surface of said blade increases in a direction from a front of said leading surface to a rear of said leading surface.

13. A blade according to claim 12, wherein said leading surface is flat.

14. A blade according to claim 12, wherein said leading surface is curved.

15. A blade according to claim 12, wherein at least a portion of said leading surface is concave.

16. A blade according to claim 11, wherein said steering element is integrated with said blade.

17. A blade according to claim 11, wherein said steering element is connected to said blade.

18. A blade according to claim 11, wherein said flat surface is planar.

20. A blade according to claim 11, wherein a layer of adhesive is positioned between said flat surface and a bottom surface of said steering element.

21. A blade according to claim 11, wherein said blade is pivotally attached with respect to a body of an arrowhead.
