The invention comprises a ratchet style open end wrench which incorporates an assembly to provide a torqueing function and ratchet effect. The assembly includes a wrench body capable of providing torque delivery through two or more rotating cylindrical cams which contact the nut. The cylindrical cams then rotate when reversing the direction of the wrench assembly so that a cutout portion of the cylindrical cams allows the nut points to pass by. In one embodiment, the direction of the ratchet effect is reversible by a reversing arc wire which is activated by use of a lever.
