Abstract

A bat having a handle inner shaft and a grip sleeve surrounding and radially spaced from the handle inner shaft.

1 . A bat, comprising;
 a barrel section, a tapering portion and a handle including a relatively small-diameter handle inner shaft extending from and integrally formed with said tapering portion, a knob affixed to a proximal end of the handle inner shaft, and   a grip sleeve surrounding and radially spaced from said handle inner shaft by a pair of rings oppositely disposed between said handle inner shaft and said grip sleeve.   
     
     
         2 . The bat of  claim 1 , wherein said handle inner shaft has a diameter less than 0.65 inches and the grip sleeve as an inner diameter at least 0.05 inches greater than the outer diameter of the handle inner shaft. 
     
     
         3 . The bat of  claim 1 , wherein said handle inner shaft has a diameter that is between 0.05 and 0.3 inches less than inner diameter of said grip sleeve. 
     
     
         4 . The bat of  claim 1 , further comprising a cylindrical foam insert positioned between said handle inner shaft and said grip sleeve. 
     
     
         5 . The bat of  claim 1 , wherein said pair of rings are formed from a soft plastic or nylon material or a semi rigid elastomeric material. 
     
     
         6 . The bat of  claim 3  wherein said cylindrical foam insert is formed from a high or medium high density polymer foam material.
