Abstract
Abstract An arrowhead for attachment to an arrow shaft including a base for abutting the end of the shaft in which the base includes an opening in its center for receiving a fastener for securing the arrowhead to the shaft end. A plurality of support sides are connected to and extend generally perpendicular from the base and blades extend from the edges of the sides. The sides are generally rectangularly shaped and the blades are generally triangularly shaped. The method of making the arrowhead includes making a hole in a flat metal body having a variety of shapes, cutting a plurality of slits in the body extending from the outer edge of the body towards the center, bending the cut edges outwardly to form a blade at each cut edge, and bending the sides generally perpendicularly to the base for support.

Claim 5
Dependent Claim
68 words
An arrowhead for attachment to an arrow shaft comprising, a base abutting the end of the shaft, said base including an opening for receiving a fastener for securing the base of said shaft end, a plurality of support sides extending from said base, an outwardly extending blade connected to each side, and a point extends from the free edge of each side and is directed toward the base.
Claim 6
Dependent Claim
68 words
An arrowhead for attachment to an arrow shaft comprising, a base abutting the end of the shaft, said base including an opening for receiving a fastener for securing the base of said shaft end, a plurality of support sides extending from said base, an outwardly extending blade connected to each side, and a point extends from the free edge of each side and is directed toward the base.
Claim 7
Dependent Claim
86 words
An arrowhead for attachment to an arrow shaft comprising, a flat base for abutting the end of the shaft, said base including an opening in its center for receiving a fastener for securing the base to said shaft, a plurality of support sides connected to said base and extending generally perpendicular to said base for enclosing the end of the shaft, and a blade connected to each outer edge of said sides extending outwardly from said sides and in a plane generally perpendicular to said base.
Claim 8
Dependent Claim
86 words
An arrowhead for attachment to an arrow shaft comprising, a flat base for abutting the end of the shaft, said base including an opening in its center for receiving a fastener for securing the base to said shaft, a plurality of support sides connected to said base and extending generally perpendicular to said base for enclosing the end of the shaft, and a blade connected to each outer edge of said sides extending outwardly from said sides and in a plane generally perpendicular to said base.
Claim 9
Dependent Claim
19 words
The apparatus of claim 4 wherein the sides are generally rectangularly shaped and the blades are generally triangularly shaped.
Claim 10
Independent Claim
94 words
The method of making an arrowhead for attachment to an arrow shaft comprising, making a hole in a flat metal body, cutting a plurality of slits in said body extending from the outer periphery of the body toward the center of the body to form a plurality of sides, bending the cut edges outwardly to form a blade at each cut edge, and folding the sides in a direction opposite to the direction of bending the cut edges to form a plurality of support sides generally perpendicular to the plane of the cut hole.
Claim 11
Independent Claim
94 words
The method of making an arrowhead for attachment to an arrow shaft comprising, making a hole in a flat metal body, cutting a plurality of slits in said body extending from the outer periphery of the body toward the center of the body to form a plurality of sides, bending the cut edges outwardly to form a blade at each cut edge, and folding the sides in a direction opposite to the direction of bending the cut edges to form a plurality of support sides generally perpendicular to the plane of the cut hole.
Claim 12
Dependent Claim
18 words

Claim 13
Dependent Claim
30 words
The method of claim 7 wherein the body is a square, and the slits are cut from the corners of the square inwardly towards but not extending to the hole.
Claim 14
Dependent Claim
32 words
The method of claim 7 wherein the body is a square, and the slits are cut from a midpoint of each side and extend inwardly towards but not extending to the hole.
Claim 15
Dependent Claim
19 words
The method of claim 9 including, bending the free ends of the sides upwardly to form upwardly directed points.
Claim 16
Dependent Claim
16 words
The method of claim 7 wherein the cut edges are bent to form triangularly shaped blades.
Claim 17
Independent Claim
57 words
The method of making an arrowhead for attachment to an arrow shaft comprising, making a hole in the center of a flat metal body, bending the outer edges of the body downwardly to form a base about the hole and generally perpendicularly extending sides, and forming generally triangularly shaped blades at the outer edges of each side.
Claim 18
Independent Claim
57 words
