Abstract: The “DISC LAUNCHING MECHANISM AND METHOD” was originally invented due to common flaws seen in most youth baseball/softball swings which is an inadequate grip and rolling the top hand over too soon which causes the bat to jump off the intended swing path and ultimately leads to a miss or inaccurate strike. With the present invention, that would equate to poor disc flight. The axe-shaped handle naturally promotes a proper baseball/softball grip. Incorporating a disc, resting on a flat shaft and anchored with spring holding mechanisms and using a tacky surface under the back of the disc to create drag, allows the disc to be held in place until the proper speed and swing-angle are reached. In testing the present invention, it was observed that it could be used for any disc launching entertainment such as disc golf or disc home run derby.
