Where does the maple wood come from? It depends on the company. For instance, Louisville Slugger has its own wood production company, but also outsources with a few different timber companies, most of them in the New York/Pennsylvania area. Holman uses a company out of the Catskills, which he says produces better quality maple.
Bats are usually made of ashe, maple and bamboo. The pros seem
to perfer maple bats, but MLB may prohibit their use due to
splintering issues and potential player injuries.
