Abstract
Abstract A molded plastic replacement handle for a tool, such as a sledge hammer, which includes an opening tapered from both ends so that the narrower part is located close to the center of the tool. A plastic adapter element is dimensioned to fit over one end of the handle and includes a tapered area in the same general direction as the bottom taper in the opening in the tool. After placement of the adapter element on the handle, the tool is placed on the adapter element. A metal insert having an opening therein is dimensioned to fit over to enter space between the top tapered area of the tool and the handle. The metal insert includes bottom sections disposed to bend inwardly into the space when the insert is forced downwardly to secure the tool to the top of the handle.
