First Claim
Patent Images
1. An arrowhead comprising:
- a body extending from a forward end to an opposing rearward end;
a first cuffing edge and a second cutting edge disposed at the forward end of the body; and
a first facet extending between the first cutting edge and the second cutting edge, the first facet comprising;
a primary facet portion at least partially disposed between the first cutting edge and the second cutting edge; and
a first bevel extending from the first cutting edge to the primary facet portion along at least a portion of the length of the first cutting edge, the first bevel and primary facet portion intersecting at a bevel boundary forming a corner, at least a portion of the first bevel being concave.

Abstract
Faceted cutting tips or forward leading ends of arrowheads having a sharp cutting edge at the juncture of adjoining facets. A bevel or bevels substantially follow(s) the contour of each cutting edge and is disposed adjacent each respective cutting edge. The facets may have at least portions thereof concave, convex or flat, as well as may the corresponding bevel(s). The structural facet integrity of the cutting tip is retained so as to sufficiently crush/split heavy bone and push penetrated material easily from its cutting path, while concomitantly slicing soft tissue with the ease of a razor edge.

30. An arrowhead comprising:
-
a body having a central longitudinal axis extending from a forward end to an opposing rearward end;
a first cutting edge disposed at the forward end of the body;
a first facet extending from the first cutting edge on a first side of the first cutting edge; and
a second facet extending from the first cutting edge on a second side of the first cutting edge, the first facet comprising;
a first primary facet portion at least partially disposed between the first cutting edge and the second cutting edge; and
a first bevel extending from the first cutting edge to the first primary fact portion along at least a portion of the length of the first cutting edge, the first bevel and first primary facet portion intersecting at a bevel boundary, the first bevel being configured such that when viewed in a plane extending through the first bevel perpendicular to the central longitudinal axis of the body, the plane intersecting the first cutting edge at an apex, the following angles are formed;
a first inside angle extending from the apex to points intersecting the first bevel and the second facet at a first radius from the apex; and
a second inside angle extending from the apex to points intersecting the first primary facet portion and second facet at a second radius from the apex, the first inside angle being smaller than the second inside angle. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. An arrowhead comprising:
-
a body extending from a forward end to an opposing rearward end;
a first cutting edge and a second cutting edge disposed at the forward end of the body, the first cutting edge having a forward most terminus and a rearward most terminus, and the second cutting edge having a forward most terminus and a rearward most terminus; and
a facet extending between the first cutting edge and the second cutting edge, the facet comprising;
a primary facet portion at least partially disposed between the first cutting edge and the second cutting edge; and
a first bevel extending from the first cutting edge to the primary facet portion along at least a portion of the length of the first cutting edge, the first bevel having an exterior surface, the facet being configured such that the entire exterior surface of the first bevel does not lie in a plane intersecting the forward most and the rearward most terminuses of both the first and second cutting edges. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51)

52. An arrowhead comprising:
-
a body extending from a forward end to an opposing rearward end;
a first cutting edge and a second cutting edge disposed at the forward end of the body, the first cutting edge having a forward most terminus and a rearward most terminus, and the second cutting edge having a forward most terminus and a rearward most terminus; and
