Mechanics and hand-eye coordination are not the only critical aspects to hitting. Building bat speed optimizes an athletes playing potential. We have been doing extensive research to deliver great training tools made out of our quality wood. We incorporate multiple tools to get the job done. Our Double Knob Trainer has a variety of uses that allows athletes to hone in on building speed, strength, and agility. As a supplement to the Double Knob Trainer, we also utilize heavy bats, thin bats, our Sweet Tater, and short one handed bats.
