8. The knob of claim 4 , wherein the knob ring comprises a hard plastic body or is a sleeve comprising elastomeric material.
9. The knob of claim 1 , wherein the outer member and the inner member comprise nylon, acrylic, polyethylene, or a polymeric resin reinforced with at least one of carbon fibers, aramid fibers, or glass fibers.
10. A ball bat comprising a handle portion for holding and having a proximal end, a barrel portion for striking, a tapered mid-section connecting the handle portion and the barrel portion, and a knob comprising an inner member mounted adjacent the proximal end of the handle portion and an outer member movable relative to the inner member, the outer member comprising a hand-engaging surface for engaging a portion of a hand of a player holding the handle portion, wherein the outer member is configured to rotate relative to the inner member about an axis different from a longitudinal axis of the ball bat such that the hand-engaging surface follows the player's hand portion when the player swings the ball bat.
11. The bat of claim 10 , wherein the knob comprises a spherical bearing, the inner member being an inner race of the spherical bearing and the outer member being an outer race of the spherical bearing.
12. The ball bat of claim 10 , wherein the inner member and the outer member are dimensioned such that the knob has an external diameter between 1.5 inches and 2.5 inches.
13. The ball bat of claim 10 , wherein the knob comprises a knob ring mounted onto the outer member.
14. The ball bat of claim 13 , wherein the knob ring is interchangeable.
15. The ball bat of claim 13 , wherein the outer member, the inner member, and the knob ring are dimensioned such that the knob has an external diameter between 1.5 inches and 2.5 inches.
16. A ball bat comprising a handle portion for holding and having a proximal end with a knob portion, a barrel portion for striking, a tapered mid-section connecting the handle portion and the barrel portion, and a knob movable relative to the bat knob portion, the knob comprising a hand-engaging surface for engaging a portion of a hand of a player holding the handle portion, wherein the knob is configured to rotate relative to the bat knob portion about an axis different from a longitudinal axis of the ball bat such that the hand-engaging surface follows the player's hand portion when the player swings the ball bat.
