Abstract
An elongated wrench handle has a yoke at each end. A wrench head is pivotally mounted in each yoke, and each wrench head has two sets of wrenching surfaces. The wrench head can be rotated in its yoke to expose, in an outer operative position, either of the wrenching surfaces. The wrench head closely fits within the yoke so that a maximum torque can be transferred from the wrench handle to the selected wrenching surface.
