Abstract
Abstract By covering a grip of a metallic bat with a grip cover made of hard rubber and forcing at least one pin or cotter to penetrate through grip end and the grip, the metallic bat of the present invention can avoid the disadvantage of conventional metallic bats whereby the grip may become removed and fly out from the grip cover to cause an unforeseen accident on swinging the bat. It is thus possible to provide a safe and functional metallic bat.
