Abstract

Designs for expandable broadhead arrowheads with chisel tips for attachment to arrow shafts are provided. The chisel tips, when inserted into the ferrules of the expandable broadheads, provide greater durability, improved flight characteristics for the projectile to which the broadheads are attached, and more effective deployment of the cutting blades of the expandable broadheads.

Claims

1. An expandable broadhead for attachment to an arrow shaft, comprising:

a ferrule body comprising a nose section and at least one blade recess;

a chisel tip inserted into the nose section of the ferrule body;

a plurality of blades residing at least in part in the at least one blade recess, wherein the plurality of blades can be configured in a retracted configuration or a deployed configuration; and

a shock-absorbing retainer, releasably engaged with the plurality of blades, to retain the blades in the retracted configuration until impact.

2. The expandable broadhead of claim 1, wherein the ferrule body is comprised of a material selected from the group consisting of aluminum, titanium, magnesium, and carbon-fiber reinforced polymer.

3. The expandable broadhead of claim 1, wherein the chisel tip is comprised of a material selected from the group consisting of stainless steels, tool steels, carbides, titanium alloys, tungsten alloys, and tungsten carbides.

4. The expandable broadhead of claim 3, wherein the chisel tip is coated with a material selected from the group consisting of nickel, zinc, cadmium, and black oxide.

5. The expandable broadhead of claim 1, wherein the chisel tip is coated with a friction reducing material selected from the group consisting of a PTFE (polytetrafluoroethylene), fluoropolymer, PVD (physical vapor deposition) ceramic type coating and a CVD (chemical vapor deposition) ceramic type coating.

6. The expandable broadhead of claim 1, wherein the shock-absorbing retainer comprises a collar.

7. The expandable broadhead of claim 1, wherein each of the plurality of blades comprises a cutting edge, and wherein the cutting edge is exposed in the deployed configuration of the plurality of blades.

8. The expandable broadhead of claim 7, wherein each of the plurality of blades comprises a blunt edge, and wherein the blunt edge is exposed in the retracted configuration of the plurality of blades.

9. The expandable broadhead of claim 1, wherein the chisel tip is multi-faceted.

10. The expandable broadhead of claim 9, wherein the number of facets of the chisel tip is a multiple of the number of the plurality of blades.

11. The expandable broadhead of claim 10, wherein the chisel tip is a three-facet chisel tip.

12. The expandable broadhead of claim 10, wherein the chisel tip is a four-facet chisel tip.

13. The expandable broadhead of claim 10, wherein the facets of the chisel tip are concave.

14. The expandable broadhead of claim 10, further comprising cutting edges between the facets of the chisel tip.

15. The expandable broadhead of claim 14, wherein the cutting edges are helical blades.

16. The expandable broadhead of claim 14, wherein the cutting edges of the chisel tip bisect the separation angles of the plurality of blades.

17. The expandable broadhead of claim 9, wherein the number of facets of the chisel tip is different than the number of the plurality of blades.

18. The expandable broadhead of claim 1, wherein the expandable broadhead has a cutting diameter of about 1 inch to about 2.5 inches in diameter.

19. The expandable broadhead of claim 1, wherein the expandable broadhead has a weight of about 75 grains to about 150 grains.
