Abstract: In a preferred embodiment, slip joint pliers have a push-button which moves transversely through the adjacent bodies of the pivot portions of the pliers members, to release intermittently one of the plier members to permit a pivot element to slide from one pivot position to an alternate pivot position in the other remaining pliers member, by moving axially an enlarged portion of the pivot element to allow the movement to the alternate pivot position before returning the enlaged portion to the normal pivot location.

Abstract: In a preferred embodiment of the invention, a hand wrench handle includes on an end thereof a socket-mounting passage-forming structure having mounted therein a revolvable socket of cylindrical shape shiftable axially along a longitudinal axis of the cylindrically-shaped socket between alternate first and second positions, in a first position circumscribing teeth being engaged with a first ratchet key locking against movement in one of clockwise and counter-clockwise directions, and in a second position circumscribing other teeth being engaged with a second ratchet key locking against movement in a remaining other one of clockwise and counter-clockwise directions, with the socket being intermittently secured in one or the other of the alternate positions and shiftable therebetween by a mounted biasing spring mounted on the socket-mounting passage-forming structure pressing a ball into alternate parallel circumscribing grooves on the outer wall of the socket.
