Patent ID: 7300357

Claim:
A non-standard practice sport projectile for use within a relatively small geographic area, the non-standard projectile for practicing a striking motion associated with a sport, the non-standard sport projectile comprising: a generally rigid body comprising a material with a high flexural modulus, the generally rigid body having an external surface and a geometric center; at least one linear through hole extending completely through the generally rigid body about its geometric center, to create at least one first-surface-opening on the external surface of the generally rigid body, and to create at least one second-surface-opening on the external surface of the generally rigid body at a location that is opposite the at least one first-surface-opening, a remaining portion of the generally rigid body being devoid of through holes; and the generally rigid body having at least one strike surface on the external surface, such that striking the strike surface causes the generally rigid body to move in a direction, and with a rotation of the generally rigid body about an axis defined by the at least one through hole that provides a relatively high aerodynamic phase, and provides a relatively low aerodynamic phase as the at least one linear through hole rotates between being parallel and perpendicular to a direction of flight and causes the generally rigid body to move over a trajectory that substantially mimics a trajectory of a standard sports projectile but over a distance substantially reduced from a distance the standard sports projectile travels.
