Arrowhead with a pivotal blade selectively positionable in a plurality of different cutting diameters
First Claim
1. An arrowhead comprising:
- (a) an arrowhead body having a central longitudinal axis; and
(b) a pivotal cutting blade rotatably mounted to said arrowhead body such that when the arrowhead is penetrating an object said blade abuts against a blade-stop surface so that a furthest cutting section of said blade from said central longitudinal axis is disposed a first shortest distance from said central longitudinal axis, said arrowhead being enabled to have said furthest cutting section of said blade disposed at a second different shortest distance from said central longitudinal axis when said blade is rotatably mounted to said arrowhead body and is abutting against a blade-stop surface when the arrowhead is penetrating an object.

Abstract
An arrowhead having a pivotal blade rotatably mounted to a corresponding arrowhead body such that the pivotal blade is selectively positionable at different cutting diameters when in corresponding different penetrating configurations so as to enable the arrowhead to have differing penetration and tissue volume cutting capacities. The hinge structure rotatably mounting the pivotal blade to its arrowhead body is positionable at a plurality of different spatial locations relative to the arrowhead body. The blade stop surface, such as a sloped blade abutting surface of a blade stop washer, that the pivotal blade abuts against when penetrating an object or when rotated to an open position is positionable at a plurality of different spatial locations and/or orientations relative to the arrowhead body.

12. An arrowhead comprising:
-
(a) an arrowhead body having a central longitudinal axis; (b) a pivotal blade having a cutting edge, said pivotal blade being exposed from only one side of said arrowhead body when the arrowhead is in an in-flight configuration and when the arrowhead is in a penetrating configuration; (c) hinge means for pivotally connecting said blade to said arrowhead body so as to enable said blade to rotate relative to said arrowhead body; and (d) cutting diameter selection means for enabling said pivotal blade to define a plurality of different cutting diameters. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

30. An arrowhead comprising:
-
(a) an arrowhead body having a central longitudinal axis; (b) a plurality of pivotal blades each having a cutting edge; (c) hinge means for pivotally connecting each said blade to said arrowhead body so as to enable said blades to rotate relative to said arrowhead body, said arrowhead being configured such that a first line, perpendicular to the cutting edge of a first said blade, that intersects a cross-sectional center of the hinge means pivotally connecting said first blade to said arrowhead body is not collinear with a second line, said second line being perpendicular to the cutting edge of a second said blade and intersecting a cross-sectional center of the hinge means pivotally connecting said second blade to said arrowhead body; and (d) cutting diameter selection means for enabling said pivotal blades to define a plurality of different cutting diameters. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)

74. A blade-opening arrowhead comprising:
-
(a) an arrowhead body having a central longitudinal axis and a recessed annular groove; (b) a plurality of blade-stop washers each having a different sloped blade abutting surface than one another, each said blade-stop washer being individually removably attachable with said arrowhead body; (c) a pivotal blade having a cutting edge and an apeture; and (d) an annular blade ring having at least one bump formed thereon, said blade ring pivotally connecting said blade to said arrowhead body when extended through said blade apeture and when received within said recessed annular groove, wherein said blade, when pivotally connected to said arrowhead body so as to be seated on said bump and when rotated to an open position so as to be in abutment against a first sloped blade abutting surface of a first said blade-stop washer that is individually attached to said arrowhead body, defines a different cutting diameter than the cutting diameter defined by said blade when pivotally connected to said arrowhead body and when rotated to an open position so as to be in abutment against a second different sloped blade abutting surface of a second said blade-stop washer that is individually attached to said arrowhead body. - View Dependent Claims (75, 76, 77, 78, 79, 80)
