ABSTRACT:
A tool is provided with a handle extension, including inner and outer telescoping members. The inner member is press-fitted to the handle of the tool, and the outer member is configured to provide a comfortable grip for the user of the tool. A spring-loaded detent means between the inner and outer members provides two alternate positions, constituting a normal position in which the outer member is disposed radially of the inner member (and of the handle of the tool) and an extended position in which the outer member is disposed rearwardly of the handle of the tool for providing increased manual leverage in using the tool. In a preferred embodiment, the tool is a ratchet wrench and the telescoping members are molded of a suitable plastic.
