Broadhead having both deployable and fixed cutting blades
A non-limiting exemplary embodiment of a broadhead includes a ferrule having a multi-faceted tip, a plurality of cutting blades fixedly attached to the ferrule, and a plurality of deployable blades coupled to the ferrule.
1. A broadhead, comprising:
a ferrule, comprising:
a multi-faceted tip;
at least one blade recess; and
at least one cutting channel;
a plurality of fixed cutting blades attached to the ferrule; and
a plurality of deployable blades residing at least in part in the at least one blade recess and coupled with the ferrule, each deployable blade comprising:
a leading edge; and
a sharp cutting edge.
2. The broadhead of claim 1 , comprising a retaining device for releasably retaining the plurality of deployable blades in a retracted configuration until impact.
3. The broadhead of claim 1 , wherein the multi-faceted tip comprises cutting edges between facets.
4. The broadhead of claim 3 , wherein each cutting edge of the multi-faceted tip is either a straight line edge or a curved line edge.
5. The broadhead of claim 3 , wherein the cutting edges of the multi-faceted tip are offset from the cutting blades and from the deployable blades.
6. The broadhead of claim 3 , wherein the cutting edges of the multi-faceted tip are offset from either the cutting blades or the deployable blades.
7. The broadhead of claim 3 , wherein the cutting edges of the multi-faceted tip, the cutting blades, and the deployable blades are offset from each other.
8. The broadhead of claim 3 , wherein the number of cutting edges of the multi-faceted tip is a multiple of the number of deployable blades.
9. The broadhead of claim 3 , wherein the number of cutting edges of the multi-faceted tip is a multiple of the number of cutting blades.
10. The broadhead of claim 3 , wherein both the number of cutting blades and the number of cutting edges of the multi-faceted tip are multiples of the number of deployable blades.
11. The broadhead of claim 1 , wherein the multi-faceted tip comprises a helical pattern having spiraling cutting edges between facets.
12. The broadhead of claim 1 , wherein the multi-faceted tip comprises a plurality of facets wherein at least one of the plurality of facets comprises a curved surface.
13. The broadhead of claim 1 , wherein the ferrule is configured for relieving fluid pressure.
14. The broadhead of claim 1 , wherein at least one facet of the multi-faceted tip and the at least one cutting channel are contiguous.
15. The broadhead of claim 1 , wherein at least one facet of the multi-faceted tip and the at least one blade recess are contiguous.
16. The broadhead of claim 1 , wherein the at least one cutting channel is curved.
17. The broadhead of claim 1 , wherein the at least one cutting channel is serpentine.
18. The broadhead of claim 1 , wherein the at least one blade recess is configured as a cutting channel.
19. The broadhead of claim 1 , wherein the number of cutting blades is a multiple of the number of deployable blades.
20. The broadhead of claim 1 , wherein the cutting blades are offset from the deployable blades.
21. The broadhead of claim 1 , comprising a center of mass distal of a center of the broadhead.
22. The broadhead of claim 1 , configured for one or more of:
increasing rotation of the broadhead;
reducing drag; and
reducing the effect of cross-wind.
23. The broadhead of claim 1 , wherein the deployable blades are replaceable.
24. The broadhead of claim 1 , wherein each of the plurality of deployable blades is configured for translating proximally along a longitudinal axis of the ferrule and for radial rotation of a rear portion of the deployable blade away from the ferrule.
25. A broadhead, comprising:
a ferrule, comprising:
a multi-faceted tip; and
at least one blade recess;
wherein at least one facet of the multi-faceted tip and the at least one blade recess are contiguous;
a plurality of fixed cutting blades attached to the ferrule; and
a plurality of deployable blades residing at least in part in the at least one blade recess and coupled with the ferrule, each deployable blade comprising:
a leading edge; and
a sharp cutting edge.
26. A broadhead, comprising:
a ferrule, comprising:
a multi-faceted tip; and
at least one blade recess configured as a cutting channel;
a plurality of fixed cutting blades attached to the ferrule; and
a plurality of deployable blades residing at least in part in the at least one blade recess and coupled with the ferrule, each deployable blade comprising:
a leading edge; and
a sharp cutting edge.
27. A broadhead, comprising:
a ferrule, comprising:
a multi-faceted tip; and
at least one blade recess;
a plurality of fixed cutting blades attached to the ferrule;
a plurality of deployable blades residing at least in part in the at least one blade recess and coupled with the ferrule, each deployable blade comprising:
a leading edge; and
a sharp cutting edge; and
a center of mass distal of a center of the broadhead.
