Abstract

The present invention provides a ball bat including an elongated tubular metal body having a barrel portion at one end and a handle portion at an opposite end. The handle portion terminates a knob that includes a metal collar that extends from the handle portion and a plug that is retained in an opening in the collar. Preferably, the opening in the collar is substantially perpendicular to a longitudinal axis of the elongated tubular metal body and has a diameter that is greater than the diameter of the handle portion. The plug is preferably retained in the opening by means of a snap-fit connection between an edge that defines the opening and a groove in the plug or by means of a bayonet coupling between the plug-and the collar. A portion of the exposed surface of the plug can be used to provide an extended gripping surface.
