The wood from hickories is often used in the manufacture of items such as paddles, furniture, and drumsticks today. It also used to be a common material for early aircraft. Wood chips can be used to smoke meat in order to create a distinctive flavor. Hickories can live hundreds of years in the wild; they bear fruit even at 300 years old!
