Abstract: A typical jackhammer has a pair of handles arranged in line normal to but at opposite sides of the vertical centerline of the elongated jackhammer body. Frequently one of these handles breaks off and renders the tool inoperative. The present invention provides a simple replacement handle that is easily installed in substitution for the broken-off handle, comprising a Y-shaped steel plate in which the arms of the "Y" bolt to the jackhammer body and the leg of the "Y" projects outwardly in line with and in opposition to the remaining handle. The leg of the "Y" is fitted with additional metal portions to give the leg a rounded section that closely simulates the original handle. Thus bolted in place, the replacement handle substantially restores the tool to operative condition.
