Are there other types of drumstick grips?

Aside from the traditional and the match grip, there's the French grip, the American grip, and the Germanic grip. The French grip would be when you're holding your hands in front of you and your palms are facing each other, and then the fulcrum, which is the point where you hold the sticks, would be between your thumb and the first knuckle of your index finger. There's a pivot point, like on a seesaw or a pendulum on a grandfather's clock, and you hold it a third of the way up the stick. The Germanic and the American grip are both more palm-down, where you're holding the sticks at a 45-degree angle, but again, your palms would be facing more down.
