Abstract

A serrated blade for an arrowhead, a crossbow bolt and/or another suitable projectile. The blade has a first blade surface that intersects with a second blade surface to form at least one cutting edge. The blade also has a mixed serration section of at least one small serration and at least one large serration. The mixed serration section is positioned adjacent to at least one cutting edge. The serrated configuration of this invention allows the blade to cut in a saw-like manner as the blade passes in a forward direction through a target material.

Claims

1. A blade for an arrowhead, the blade comprising:

a body having a first blade surface and a second blade surface, at least a portion of said first blade surface intersecting with at least a portion of said second blade surface to form at least one cutting edge, a mixed serration section of at least one first serration each having a first length positioned adjacent at least one second serration each having a second length less than said first length, and said mixed serration section positioned adjacent a straight section of at least one cutting edge.

2. The blade according to claim 1, wherein said at least one cutting edge is positioned along a cutting line, and from a point on said cutting line each said first serration extends further into said first blade surface than into said second blade surface.

3. The blade according to claim 1, wherein said at least one cutting edge is positioned along a cutting line, and from a point on said cutting line each said second serration extends further into said first blade surface than into said second blade surface.

4. The blade according to claim 1, wherein said at least one first serration has a first radius of curvature, and said at least one second serration has a second radius of curvature that is less than said first radius of curvature.

5. The blade according to claim 4, wherein said at least one cutting edge is positioned along a cutting line, and said first radius of curvature and/or said second radius of curvature is within a plane containing said cutting line.

6. The blade according to claim 1, wherein said mixed serration section includes at least two said second serrations.

7. The blade according to claim 1, wherein said mixed serration section includes at least one alternating serrations pattern of two said second serrations adjacent each other and adjacent said first serration.

8. The blade according to claim 1, wherein said mixed serration section includes at least one alternating serrations pattern of two said second serrations adjacent each other and adjacent said first serration.

9. The blade according to claim 1, wherein a first said cutting edge is positioned at an outer portion of said body and a second said cutting edge is positioned at an inner portion of said body.

10. The blade according to claim 9, wherein said mixed serration section includes at least two adjacent said second serrations positioned next to a straight section of said at least one cutting edge.

11. The blade according to claim 10, wherein at least one said first serration is positioned between each pair of said two said second serrations.

12. The blade according to claim 10, wherein two said first serrations each is positioned between each pair of said two said second serrations, and at least one said second serration is positioned between both said first serrations.

13. The blade according to claim 1, wherein said first blade surface and/or said second blade surface is generally planar.

14. The blade according to claim 1, wherein said first blade surface and/or said second blade surface is generally curved.

17. The blade according to claim 1, wherein said mixed serration section includes at least one alternating serrations pattern of two said second serrations adjacent each other and adjacent said first serration.

15. A blade for an arrowhead, the blade comprising:

a body having a first blade surface and a second blade surface intersecting with said first blade surface and forming a cutting edge, a mixed serration section of at least one first serration positioned adjacent at least one second serration, said second serration being smaller than said first serration, and said mixed serration section positioned adjacent said at least one cutting edge.

16. The blade according to claim 15, wherein said mixed serration section is positioned adjacent a straight section of said cutting edge.
