Abstract
A hand tool includes a handle and an arm assembly. The handle has a mounting portion. A square peg on the mounting portion is removably secured in a square hole in a base of the arm assembly. The arm assembly includes a pair of parallel arms each have an inner end portion pivotally mounted to the base on a pair of pins which extend parallel to the axis of the peg. A tool is pivotally connected to the outer end portion of each of the parallel arms. The handle is capable of being mounted to the base of the arm assembly in a first position and in a second position rotated 180.degree. from the first position.
