Abstract

A projectile includes a body having one of a number of geometric shapes which have a plurality of blades. The projectile may be divisible into two substantially equal portions. The portions have a number of blades disposed across their respective surfaces. Moreover, a blade may encircle the periphery of the projectile and may be sandwiched between the portions once assembled to one another. In one embodiment, the blades may be removed so that they may be replaced when they become dulled through use. Alternatively, the blades may be removed, sharpened, and returned to their appropriate positions on the projectile body.

Claims

1. A projectile comprising:

a three dimensional body having an exterior surface,

said body comprised of two substantially equal portions,

said portions removably engageable with one another by an attachment means,

a plurality of grooves disposed across said exterior surface of said body,

a corresponding number of removable blades cooperating with and closely fitting within said grooves,

each of said blades projecting radially from the center of said body, each of said blades extending continually around the exterior surface of said body,

said blades having attachement means between said blades and said body portions, whereby

said blade attachement means maintains said blades within said grooves.

2. A projectile according to claim 1 wherein;

said portions of said projectile body are hollow.

3. A projectile according to claim 1 wherein;

said body portion attachment means comprises centrally located cooperating threaded fittings.

4. A projectile according to claim 1 wherein;

said blades each having an interior surface and an exterior surface,

said blade attachment means being extrusions disposed upon said interior surface whereby

said extrusions project into and closely cooperate with said body thus preventing inadvertant detachment of said blades.

5. A projectile according to claim 1 wherein;

said body comprises a substantially circular cross section.

6. A projectile according to claim 1 wherein;

said body comprises a substantially polygonal cross section.

7. A projectile according to claim 1 wherein;

said body comprises a substantially ellipsoidal cross section.

8. A projectile according to claim 2 wherein;

said body comprises a substantially circular cross section.

9. A projectile according to claim 1 wherein;

said body comprises a substantially polygonal cross section.

10. A projectile according to claim 2 wherein;

said body comprises a substantially ellipsoidal cross section.

11. A projectile according to claim 1 wherein;

said blades each having an exterior surface, and

said blade exterior surfaces form cutting edges.

12. A projectile according to claim 2 wherein;

said blades each having an exterior surface, and

said blade exterior surfaces form cutting edges.

13. A projectile according to claim 1 wherein;

said body portions are separable at the equatorial perimeter of said body,

said body equatorial perimeter contains a circumferential groove,

said circumferential groove providing means for the containment of a circumferential blade when said body portions are engaged with one another.

14. A projectile according to claim 2 wherein;

said body portions are separable at the equatorial perimeter of said body,

said body equatorial perimeter contains a circumferential groove,

said circumferential groove providing means for the containment of a circumferential blade when said body portions are engaged with one another.
