Pliers are provided. Pliers include an upper handle, a lower handle, an upper jaw coupled to the upper handle, and a lower jaw coupled to the lower handle. In general, the upper jaw includes workpiece engagement surface, such a first set of teeth configured to engage a workpiece, and the lower jaw includes a workpiece engagement surface, such as a second set of teeth and a third set of teeth. The lower jaw opposes the upper jaw such that the first set of teeth faces the second set of teeth and the third set of teeth. At least a section of the workpiece engagement surface of the lower jaw is movably coupled to the lower jaw such that it moves relative to the lower as torque is applied to a workpiece, thereby increasing torque applied to the workpiece.

Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releasably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.

A tool is provided in order to facilitate utilization by users in a wide variety of applications. By way of example, a multipurpose tool includes a first handle having a first axle and a second handle having a second axle; a first jaw and a second jaw, defining a stowed position and a deployed position, where in the stowed position the first jaw is received within the second handle and the second jaw is received within the first handle; a third jaw and a fourth jaw, defining a stowed position and a deployed position, where in the stowed position the third jaw is received within the second handle and the fourth jaw is received within the first handle, where the first jaw and fourth jaw are pivotably attached at the second axle, the second jaw and third jaw are pivotably attached at the first axle.

The invention relates to crimping pliers wherein a die comprises two die half units. The die half units each comprise a die half and a bearing body. The bearing body is supported in an associated bearing accommodation of a pliers jaw. The die halves are supported by a rotational bearing for being rotated about a crimping axis relative to the bearing body.

According to the invention it is possible to assemble and disassemble the bearing body of the die half unit to and from the bearing accommodation of the pliers jaw without the use of any tool. It is also possible that a latching or locking device is used for the assembly.

In order for hydraulic disk brakes to function properly over time, associated brake pads are changed periodically. In order to exchange old brake pads for replacement brake pads, a disk brake may require pushing back the brake pistons within a brake caliper body in order to make room for installation of replacement pads. Current tools and methods typically require removal of a wheel from a vehicle, removal of a brake rotor from the wheel, and/or removal of the brake caliper body from a rotor. The presently disclosed caliper piston tool allows brake pads to be replaced without dismantling various components of the vehicle, resulting in significant time and cost savings as well as convenience for do-it-yourself and professional mechanics alike.
