Abstract: A slip-joint pliers having opposed parallel jaws with a specific cross-hatch pyramidal teeth construction develops a high torque grip slip force on a seized or overly tightened cylindrical workpiece such as a pipe or bar. The pliers includes a tongue in groove type slip-joint construction. The cross-hatch teeth are disposed at between 110° and 150°, and the rows of cross-hatch teeth are spaced at less than about 10 teeth/inch on each jaw face. The pliers are a compact yet heavy-duty use tool that develops a torque grip slip force greater than similarly sized prior art pliers.

Abstract: A firefighter tool has pivotably connected handles and jaws, and one handle has an outer generally sinusoidal surface and the handle end is formed with a hook facingly disposed to the generally sinusoidal surface. The handles open fully so that the user grips the other handle and the sinusoidal surface hook alternately operably contactingly engages differently sized and configured fire hose couplings.

Abstract: A pliers fencing tool includes a wedge having a through slot for engagement with the rotatably mounted ratcheted sprocket teeth of a fence wire strainer suspended between the fence wire looped ends. Through slot engaged caused the teeth to rotate from a first to a second ratcheted position and thereby strain the fence wire. A grip having a thumb receiving recess and thumb guard is provided between the wedge and the means for pivotably connecting the handles, and the handles are gripped at the grip portion with the wedge distally disposed.

Abstract: A compact readily pocket stowable ergonomic grip rescue tool includes pivotally fully opened handles in an obtuse angle disposition with one handle separately gripped with hand and thumb conforming functionality. A leverage force is transmitted from the gripped handle through force bearing surfaces to the oppositely disposed handle having an outwardly disposed generally sinusoidal surface and juxtaposed hook end which engage a seized fire hose coupling. A resultant high torque force is generated by the compact pocket stowable tool to readily uncouple seized fire hose coupling.

Abstract: A rescue tool includes a fully pivotally opened handle in an obtuse angle disposition with one handle separately gripped and then a force transmitted through force bearing surfaces to the oppositely disposed handle having an outwardly disposed sinusoidal surface and juxtaposed hook end which engage a seized fire hose coupling. A high torque force is readily exerted through the handles on the seized fire hose coupling. The elongate handles and pivotally disposed jaws having elongate arcuate cutting edges corporately provide rapid cutting of aluminum sheath hybrid car battery cables in a further rescue operation.

Abstract: A cable stripping pliers has facingly disposed arcuate cutting edges formed at the ends of transversely oppositely disposed arcuate surfaces. The pliers are adjustable to two positions for the jaws to engage differently sized cables. The resilient insulation is disposed away from the arcuate surfaces when the cutting edges cut the resilient insulation for readily removing the insulation from the core material.

Abstract: A fish tape pliers is formed with opposed planar and curvilinear edges that form or channel disposed distally from the pliers' pivot connection axis. In one operable embodiment, the edges frictionally engage the fish tape within the channel. The fish tape in pulling an electrical wire through a conduit, is directed away from the handles and the users' grip hand. The jaws may have differently contoured or cross-ridged surfaces to provide the desired frictional engagement without damaging the fish tape. The fish tape pliers includes diverse complementary features for crimping, stripping, bending and/or cutting an electrical wire.

Abstract: A locknut tightening construction includes the construction of a locknut having a plurality of adjacent angularly disposed walls and pliers first and second jaws, with the first jaw having a first notch and the second jaw having a second notch, with the first notch being more elongate and distally disposed than the second notch, and the notches engage different angularly disposed locknut walls.

Abstract: The present invention is a hand tool comprising a pair of handles that rotate about a pivot point. The proximal end of the handles may be covered in an electrically insulating material in order to aid in insulating the hands of the user from electrical shock and cushion the grip of the tool. A jaw member of thin cross-section may be affixed to the distal end of the handles or formed in the distal end of the handles. The unique shape of the portion of each jaw member grips the locknut. Each jaw member is designed in such a manner that, when the hand tool's handles are closed, each jaw member independently engages one or more of the locknut protrusions. A method of tightening and loosening locknuts using a hand tool with the distal end of the handles forming a shaped jaw member for gripping the locknut.

Abstract: A grinder attachment for precision grinding with an existing grinding machine having an external housing and a driven shaft rotatable about a grinding machine axis at a predetermined rotational speed when energized includes a driving pulley wheel having a first diameter attachable on the driven shaft for rotation therewith about the machine axis. The attachment to the housing is rigidly attached to the external housing of the grinding machine to substantially prevent any movements of the attachment housing in a three-dimensional space relative to the external housing in the grinding machine. A spindle is rotatably mounted on the attachment housing. A driven pulley wheel is fixedly mounted on a spindle to rotate with the spindle, a grinding abrasive element being mounted on the spindle at a grinding station for rotation therewith. Pulleys are mechanically coupled to cause rotation of the driven pulley when the driving pulley is rotated by the grinding machine.

Abstract: Adjustable jaw plier tool having crossed pivotably engaged handles one of which is slotted, and one of which has an affixed pivot pin. An integral over travel element is positioned on the rearward portion of the working surface of the jaw of the handle having the affixed pivot pin to avoid the possibility of hand injury by bearing against an elongate portion of the slotted handle.

Abstract: A pivot connection for slip joint pliers in which a rivet has a shank with a preformed head at one end overlapping one of the plier halves to be connected, and the other end of the shank is headed over the other plier half and expanded into a hole in the other plier half tapered outwardly at a locking taper angle.
