Abstract

An archery arrowhead including having a nose and at least one projection having a forward facing leading edge. In one embodiment, the arrowhead includes at least three projections, and the nose is blunt. The projections can be fixed and immovable relative to the arrowhead and the leading edges can be sharpened. The nose and the projections can form a unitary, monolithic body. Optionally, the leading edge can be curvilinear, linear or a combination curvilinear/linear. The edge can be sharpened to provide a cutting surface on the projection. The arrowhead can be manufactured using a variety of techniques including Powder Injection Molding (PIM), casting, molding, machining, and the like.

Claims

1. An archery arrowhead comprising:

a base including threads adapted to thread into an arrow insert;

a body joined with the base;

a blunt nose extending forwardly from the body;

a plurality of projections extending fixedly from the body, each projection including a leading edge, the leading edge including a corner and a sharpened edge with an area defined therebetween, at least one portion of the sharpened edge being disposed at a positive angle, whereby the blunt nose provides an impact surface to stun game impacted by the arrowhead, and whereby the sharpened edge provides a cutting surface to substantially simultaneously penetrate the game impacted by the arrowhead.

2. The archery arrowhead of claim 1 wherein the body, blunt nose and plurality of projections form an integral, monolithic unit.

3. The archery arrowhead of claim 1 wherein at least two projections extend from the body.

4. The archery arrowhead of claim 1 wherein the sharpened edge is curvilinear.

5. The archery arrowhead of claim 1 wherein the sharpened edge includes a first portion at a first positive angle, a second portion at a second positive angle, and a third portion at a negative angle.

6. The archery arrowhead of claim 5 wherein the first portion, second portion and third portion are contiguous.

7. The archery arrowhead of claim 6 wherein the first portion, second portion and third portion collectively form a curvilinear edge.

8. An archery arrowhead comprising:

a base;

a body joined with the base;

a nose projecting from the body;

a forward projecting projection extending from the body, the projection including at least one forward facing edge, whereby the nose transfers a stunning force to game impacted by the arrowhead, and whereby the edge of the projection assists in penetrating the game impacted by the arrowhead;

wherein the projection is disposed in a fixed, immovable position relative to the body.

9. An archery arrowhead comprising:

a base;

a body joined with the base;

a nose projecting from the body;

a forward projecting projection extending from the body, the projection including at least one forward facing edge, whereby the nose transfers a stunning force to game impacted by the arrowhead, and whereby the edge of the projection assists in penetrating the game impacted by the arrowhead;

wherein the edge is substantially linear.

10. An archery arrowhead comprising:

a base;

a body joined with the base;

a nose projecting from the body;

a forward projecting projection extending from the body, the projection including at least one forward facing edge, whereby the nose transfers a stunning force to game impacted by the arrowhead, and whereby the edge of the projection assists in penetrating the game impacted by the arrowhead;

wherein the edge includes a plurality of portions, at least one of the portions disposed at a positive angle and at least a different one of the portions disposed at a negative angle.

11. An archery arrowhead comprising:

a base;

a body joined with the base;

a nose projecting from the body;

a forward projecting projection extending from the body, the projection including at least one forward facing edge, whereby the nose transfers a stunning force to game impacted by the arrowhead, and whereby the edge of the projection assists in penetrating the game impacted by the arrowhead;

wherein the base, the nose, the body and the projection form a one piece, monolithic unit.

12. An archery arrowhead comprising:

a body including a blunt nose, a longitudinal axis, and a projection, the projection being fixed and immovable relative to the body and having at least a portion of a forward curving edge, the projection extending outwardly, away from the longitudinal axis.

13. An archery arrowhead comprising:

a body including a blunt nose and a projection, the projection being fixed relative to the body and having at least a portion of an edge disposed at a positive angle wherein the body, nose and projection form a one piece, monolithic unit.
