Abstract

A cut-on-contact broadhead having a plurality of deployable blades. Each of the plurality of blades is pivotally coupled to a ferrule configured for attaching the broadhead to a shaft of an arrow or a bolt. Each of the plurality of blades includes a tip, an impact region, a first cutting edge, and a second cutting edge. During flight, blades are in a fully retracted state forming a distal tip of the broadhead having sharp cutting edges defined at least in part by the first cutting edges of the blades. Upon impact, the distal tip of the broadhead creates a bore in the target. As the broadhead penetrates the target, the plurality of blades are deployed into a swept-back configuration exposing the second cutting edge of each blade. The second cutting edges expand the bore initiated by the distal tip of the broadhead and create a passage in the target.

Claims

1. A broadhead, comprising:

a ferrule comprising;

a distal end;

a proximal end;

a plurality of recesses extending proximally from proximate the distal end; and

a plurality of channels extending proximally from proximate the distal end, wherein each channel is disposed between adjacent recesses; and

a plurality of deployable blades, wherein at least a portion of each blade is disposed within and is pivotally coupled to one of the plurality of channels, each blade comprising;

a tip;

an impact region;

a first cutting edge extending from the tip to proximate the impact region; and

a second cutting edge extending from the tip to proximate the channel to which the blade is pivotally coupled;

wherein, during flight

at least a portion of the second edge of each blade is retained within at least a portion of the channel to which the blade is pivotally coupled; and

the tips of each blade converge to form a chisel tip comprising cutting edges defined at least in part by the first cutting edge of each blade.

2. The broadhead of claim 1, comprising at least one frangible collar for retaining the plurality of blades in an in-flight configuration.

3. The broadhead of claim 1, wherein the chisel tip bores into a target upon impact.

4. The broadhead of claim 1, wherein the first cutting edge of each of the plurality of blades cuts into the target to create a bore.

5. The broadhead of claim 2, wherein the frangible collar disintegrates when the target imparts a force on the impact region of each of the plurality of blades.

6. The broadhead of claim 1, wherein the plurality of blades deploy into a swept-back configuration exposing their respective second cutting edges.

7. The broadhead of claim 6, wherein each of the plurality of blades traverses a plane substantially orthogonal to a longitudinal axis of the broadhead.

8. The broadhead of claim 6, wherein the tip of each of the plurality of blades traverses an arc having a center at a location where the blade is pivotally coupled to the channel.

9. The broadhead of claim 6, wherein the second cutting edge of each of the plurality of blades cuts into the target to widen the bore as the broadhead penetrates the target.

10. The broadhead of claim 1, wherein a tip of the chisel tip is distal of the distal end of the ferrule.

11. The broadhead of claim 1, wherein a tip of the chisel tip is proximate the distal end of the ferrule.

12. The broadhead of claim 1, wherein one or more of the plurality of recesses is configured for relieving pressure as the broadhead penetrates a target.

13. The broadhead of claim 1, wherein one or more of the plurality of channels is configured for relieving pressure as the broadhead penetrates a target.

14. The broadhead of claim 1, wherein one or more of the plurality of recesses and one or more of the plurality of channels are configured for relieving pressure as the broadhead penetrates a target.

15. The broadhead of claim 1, wherein the proximal end of the ferrule is configured for attaching the broadhead to a shaft of an arrow or a bolt.

16. The broadhead of claim 1, wherein the broadhead rotates during flight and continues to rotate as the broadhead penetrates and travels within a target.
