A hand tool having a first hand tool member assembly having a jaw portion, a tension assembly, and a cam assembly and a second hand tool member assembly having a jaw portion. The hand tool further has a jaw portion first pivot point coupling the first hand tool member assembly to the second hand tool member assembly and a jaw portion second pivot point coupling the first hand tool member assembly to the second member assembly. The jaw portion second pivot point located closer to the first member and second member jaw portions than the jaw portion first pivot point. The first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion are structured to close together in a three-phase motion consisting of a first pivot phase, a transition phase and a second pivot phase, the first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion pivot relative to each other about the jaw portion first pivot point during the first pivot phase and pivot relative to each other about the jaw portion second pivot point during the second pivot phase. The cam assembly is structured to engage the tension assembly when the first hand tool member assembly jaw portion and the second hand tool member assembly jaw portion contact a workpiece thereby initiating the transition phase between the first pivot phase and the second pivot phase wherein the rotation about the jaw portion first pivot point is halted causing the jaw portions to rotate about the jaw portion second pivot point.

A clip engages a pair of legs of a vibration attenuator to reduce the local separation of the legs, thereby increasing the force of friction pads, affixed to the legs, against a brake disk to compensate for reduced thickness of the friction pads due to wear. The clip has a first end region, which can preferably be snappably engaged with one of the legs so as to pivot thereabout. The clip has a second end region with a protrusion which can be engaged with the other leg so as to restrain it at the reduced separation. Preferably, a second protrusion is provided to allow restraining the other leg at an even smaller local separation from the leg that is rotatably engaged by the first end region. A tab preferably extends beyond the first protrusion to aid in engaging and disengaging the second end region from the other leg.

An apparatus for clearing a clog in a pipe having a diameter, the apparatus including a hollow, rigid cylindrical body, the body having a closed end, an open end and an inside diameter that is less than the diameter of the pipe at the clog thereby providing a mechanical advantage in removing the clog; a piston disposed in the body for reciprocation therein; a rod attached to the piston and extending through an opening in the closed end of the body; a handle located on an upper portion of the rod; and a seal attached to the open end of the body.
