Thick As A Forest.
The 423HD is a high density birch bat with a standard knob. This model will be about a -3 in weight differential with a full cup.
The fact that wood bats break is a hard pill to swallow. We made this series with those who just spit that pill out. Not quite indestructible, but these will last, and will give you the time necessary to learn how to use these very particular tools.
Bat insurance is a 30 day warranty from date of delivery on any bat purchased through Birch Bats. Insurance is good for a one time replacement of the original ordered bat and covers the ground shipping of the replacement bat.
