These sticks are made of American hickory, the most preferred hickory for drumsticks (it comes from the Southeastern United States). The specific gravity of hickory is 0.82 at 15% moisture content. It is considered to be a hardwood even though it is not as dense or heavy as oak. This does not make hickory better or worse than oak. It's just different. That difference becomes a personal preference for the drummer.

Choosing the best drumstick is a very personal decision. Many drummers have not yet discovered how much better they could play using the correct stick. It's not unusual for professionals to use 2 or 3 different models or more.
Factors to consider when choosing a drumstick include density, straightness of grain, type of wood, weight, length, diameter, wood or nylon tip, plus the intangibles of balance and feel. When selecting a stick, look for a good quality hardwood with the grain running uniformly from butt to bead. The kind of wood selected will have a great deal to do with the feel, the balance, the sound and the longevity of the stick. Some drummers prefer the natural sound of wood tips. Others prefer nylon tips for a bright, cymbal sound and longer tip life.
