Abstract
A hand tool includes a work section and a handle section connected to the work section. The handle section has one recess defined in an outer surface thereof so as to receive a spring and a bead. An extendable portion is movably mounted to the handle section and has two dents. The extendable portion is moved relative to the hand portion by receiving the bead in one of the dents so as to have a longer arm of force when using the hand tool.
