The handle is made of "true" Hickory and the barrel of Oregon Tanoak.  The Hickory is the key to the Powerwood bat's durability and performance.  There's a reason they make axe handles from Hickory!  Tanoak is harder than maple, local, sustainable and beautiful. Harmon Killebrew and Hank Aaron, among others, swung Tanoak Oregon Slammers back in the 60's.  A little Oregon baseball history:  Back in the 1960s, Hall of Famer Harmon Killebrew was the main owner of a bat company on the coast of Oregon called Tanoak Industries, where they made the Oregon Slammer.  The guy who ran the company essentially killed it and the "knowledge" of Tanoak was lost for many years.  Until now.
