发明名称 Ball bat having grooved knob
摘要 An improved ball bat providing greater gripping comfort and batting power is provided by provision of a bat having a peripherally grooved lower terminal knob adapted to receive the small or little finger of a batter's hand. The bat construction may be used in softball or baseball bats formed of various materials such as wood or aluminum. The finger-receiving groove may extend in a continuous fashion around the entire periphery of the terminal knob, or only part way around the knob.
