ABSTRACT:
A wrench includes a handle having a head and a gear disposed in the head. A pawl is pivotally secured in the handle and has two ends selectively actuated to act onto the gear. A knob has a spring-biased projection for selectively actuating either of the ends of the pawl to engage with the gear. An indicator device may be used for indicating the active direction of the wrench by indicating the position of the knob. The pawl may be disposed outside of the gear or may be disposed in a cartridge that is rotatably received in an internal gear.
