A wrench may include a head, a drive tang that engages a work piece, a locking detent operably coupled to the drive tang, and a release button configured to control operation of the locking detent. The release button may be movable between a locked position where the locking detent locks the work piece to the drive tang and an unlocked position where the detent permits removal of the work piece from the drive tang. The wrench may also include a slide lock member configured to slide along a second direction between an engaged position and a disengaged position. In the engaged position, the slide lock member may prevent movement of the release button, and, in the disengaged position, the slide lock member may be disengaged from the release button to permit movement of the release button from the locked position to the unlocked position.

The present disclosure relates to a tool that includes a head having a cavity, and a ratchet assembly carried within the cavity and rotatable about a centerline. The ratchet assembly including a gear portion and a drive portion aligned along the centerline, and a pawl carrier rotatable within the cavity relative to the gear portion, and wherein the pawl carrier is rotatable between a first position and a second position, wherein the first position corresponds to a first pawl mechanically positioned along a groove to engage the gear portion and the second position corresponds to a second pawl mechanically positioned along the groove to engage the gear portion. The tool further includes a ratchet control including a ratchet lever configured to engaged a back surface of the head and a and a ratchet base disposed within the cavity, wherein the ratchet lever mechanically engages the ratchet base.
