Abstract
Abstract The universal replacement handle of this invention may be used with a variety of tools such as shovels having a handle-receiving socket. The handle comprises a handle member having a tool coupling section at one end thereof and a hand-grasping section extending outwardly from the tool coupling section. The tool coupling section includes a plurality of socket adaptors effective to cause the handle to fit the handle-receiving sockets of a variety of shovels selected from the group consisting of a handle back shovel with a shoulder, a Razorback® open back shovel, a lock socket shovel, a solid socket closedback shovel with a shoulder, and a solid shank closedback shovel without a shoulder. The tool coupling section includes first and second adaptor mounting sections for carrying respective first and second adaptor mechanisms having removable segments designed to adapt the handle to a particular handle-receiving socket.
