Abstract

An arrow broadhead with two sets of cutting blades: a replaceable tip cutting blade mounted on a nose portion of the broadhead; and a set of ferrule blades placed behind the nose portion and individually removable from a ferrule body of the broadhead. Each ferrule blade can be either triangular or concave in shape with a concave blade configuration giving maximum arrow penetration into the target. Dual sets of blades promote maximum penetration and broadhead durability. Damaged cutting tip blades can be removed easily and replaced without displacing non-undamaged ferrule blades. Conversely, each ferrule blade can be individually removed without displacing the cutting tip blade. Because the dual sets of blades provide maximum penetration, the present invention promotes quicker, more humane kills.

Claims

1. An arrow broadhead comprising:

a ferrule body having a plurality of axially extending ferrule slots, each said ferrule slot extending radially into said ferrule body;

a removable ferrule blade engaged in each said ferrule slot, each ferrule blade having a front end and a rear end;

means for securing the front and rear ends of each ferrule blade within the respective ferrule slot of said ferrule body;

a nose portion attachable to a front end of said ferrule body, said nose portion having at least one nose slot extending from a front end to a back end of said nose portion, each said nose slot extending substantially radially into said nose portion; and

a removable slicing tip blade engaged in each said nose slot, each said slicing tip blade being substantially triangular in shape with two sharpened outer edges and a backward edge, said backward edge extending substantially perpendicular to said back end of said nose portion.

2. An arrow broadhead according to claim 1, comprising three ferrule slots and three ferrule blades.

3. An arrow broadhead according to claim 1, wherein said nose portion includes two nose slots.

4. An arrow broadhead according to claim 1, wherein each said ferrule blade is substantially triangular in shape with a sharpened outer edge, an inner edge engaged in a respective ferrule slot and a backside edge extending substantially radially outward from said ferrule body, each said ferrule blade having a tapered region at a front end thereof, and a protrusion extending along the backside edge from the inside edge of said ferrule blade to a point flush with the outside surface of said ferrule body.

5. An arrow broadhead according to claim 4 wherein said means for securing includes:

a tapered undercut in said nose portion to substantially match the tapered region at the front end of each of said ferrule blades; and

a washer surrounding said ferrule body adjacent said rear end of each blade and engaging each of said protrusions.

6. An arrow broadhead according to claim 1, wherein each said ferrule blade includes a sharpened concave outer edge, an inner edge engaged in said ferrule slot, and a backside edge extending radially outward from said ferrule body.

7. An arrow broadhead according to claim 1, wherein each said ferrule blade and said cutting tip blade are made of 301 half hard stainless steel.

8. An arrow broadhead according to claim 1 wherein said slicing tip blade is aligned substantially coplanar with at least one of said ferrule blades.

9. A hunting arrow comprising:

an arrow shaft having a threaded cavity at its front end;

a ferrule body having a threaded tip at its back end for engaging said arrow shaft along a central axis of said shaft within the threaded cavity, said ferrule body having a plurality of longitudinally extending ferrule slots, each ferrule slot extending substantially radially into said ferrule body;

a removable ferrule blade engaged in each ferrule slot, each ferrule blade having a front end and a rear end;

means for securing the front and rear ends of each said ferrule blade within a respective ferrule slot of said ferrule body;

a nose portion attached to a front end of said ferrule body, said nose portion having at least one axially diverging nose slot extending from a front end to a back end of said nose portion, each said nose slot extending substantially radially into said nose portion; and

a removable slicing tip blade engaged in each said nose slot, each said slicing tip blade being substantially triangular in shape with two sharpened outer edges and a backward edge, said backward edge extending substantially perpendicular to said back end of said nose portion.

10. A hunting arrow according to claim 9, wherein said securing means comprises:

protrusions formed at the rear end of each ferrule blade;

a washer axially fitable over both the threaded tip of the ferrule body, and the outside surface of said protrusions of each ferrule blade engaged in said ferrule slots, said washer engaging said ferrule body to secure the rear ends of said ferrule blades into said ferrule slots;

tapered portions at said front ends of each ferrule blade; and

a tapered undercut in said nose portion to substantially match said tapered portions at said front ends of each ferrule blade.

11. A hunting arrow according to claim 9 wherein each said ferrule blade and said cutting tip blade are made of 301 half hard stainless steel.

12. A hunting arrow according to claim 9, said ferrule body having an axially diverging outside surface, a forward end of said ferrule body being of a lesser diameter than a rearward end of said ferrule body.

13. A hunting arrow according to claim 9, wherein said slicing tip blade is aligned substantially coplanar with at least one of said ferrule blades.

14. An arrow broadhead comprising:

a ferrule body having a plurality of longitudinally extending ferrule slots, each said ferrule slot extending into said ferrule body;

a removable ferrule blade engaged in each ferrule slot, each ferrule blade having a tapered region at the front end and a rear end, and having a sharpened concave outer edge, a substantially straight inner edge engaged in each said ferrule slot and a backside edge extending substantially radially outward from said ferrule body;

means for securing the front and rear ends of each said ferrule blade within a respective ferrule slot of said ferrule body;

a nose portion attachable to a front end of said ferrule body, said nose portion having a tapered undercut to substantially match the tapered region at the front end of said ferrule blade for engaging the front of each said ferrule blade with said ferrule body, and having at least one axially diverging nose slot extending substantially radially into said nose portion from a front end to a back end of said nose portion; and

a removable slicing tip blade engaged in each said nose slot, each slicing tip blade extending forward of said back end of said nose portion.

15. An arrow broadhead according to claim 14 wherein said plurality of said ferrule slots and said concave blades each equal three in number.
