Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as:
They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 240 to 300 mm (9.5 to 12 inches) long—for increased leverage. [1] [2] [3] The weight of the tool can also vary, depending on the material used.
Tongue-and-groove pliers are commonly used for turning and holding nuts and bolts, gripping irregularly shaped objects, and clamping materials. It is also possible to rotate objects while keeping them in one position.
Originally developed as a blacksmiths tool, patented in 1899 Canada under CA64246A [4] by Vernon Graham Higgins and sold out of Fortuna, California by the patentee. Advertised in the November 1899 issue of "The Blacksmith and Wheelwright", [5] an American periodical; the original variants had longer reins than the modern equivalent, and may not have had the groves in the jaws.
The current design of pliers was developed and popularized by the Champion–DeArment Tool Company in 1934 under the brand name Channellock (after which the company was later renamed) [6] but are also now produced by a number of other manufacturers.

An adjustable spanner, shifting spanner, English wrench (Turkey) or adjustable wrench is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head rather than just one fastener size, as with a conventional fixed spanner.
Meadville is a city in and the county seat of Crawford County, Pennsylvania, United States. The population was 13,050 at the 2020 census.

An electrician is a tradesperson specializing in electrical wiring of buildings, transmission lines, stationary machines, and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable lines.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.
Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe. They are also useful for bending and physically compressing a wide range of materials. Generally, pliers consist of a pair of metal first-class levers joined at a fulcrum positioned closer to one end of the levers, creating short jaws on one side of the fulcrum, and longer handles on the other side. This arrangement creates a mechanical advantage, allowing the force of the grip strength to be amplified and focused on an object with precision. The jaws can also be used to manipulate objects too small or unwieldy to be manipulated with the fingers.
Forceps are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task. The term "forceps" is used almost exclusively in the fields of biology and medicine. Outside biology and medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps.
A constant-velocity joint is a mechanical coupling which allows the shafts to rotate freely and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
Caliper(s) or calliper(s) are an instrument used to measure the dimensions of an object; namely, the diameter or depth of a hole. The word caliper comes from latin roots meaning precise pincer.
A chuck is a specialized type of clamp used to hold an object with radial symmetry, especially a cylinder. In a drill, a mill and a transmission, a chuck holds the rotating tool; in a lathe, it holds the rotating workpiece.
Crimping is a method of joining two or more pieces of metal or other ductile material by deforming one or both of them to hold the other. The bend or deformity is called the crimp. Crimping tools are used to create crimps.
A noseband is the part of a horse's bridle that encircles the nose and jaw of the horse. In English riding, where the noseband is separately attached to its own headstall or crownpiece, held independently of the bit, it is often called a cavesson or caveson noseband. In other styles of riding, a simple noseband is sometimes attached directly to the same headstall as the bit.
A vise or vice is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever.
Knipex is a German manufacturer of pliers, pliers wrenches, and other tools, distributed for global sales. Its tools are principally for professional use in various trades, but they are also increasingly popular for DIY and EDC use as well.
Irwin Industrial Tools is an American manufacturer and distributor of hand tools and power tool accessories. It is owned by Stanley Black & Decker. It is best known for producing Vise-Grip locking pliers. Additionally, it produces clamps, drill bits, taps and dies, screw extractors, bolt extractors, saw blades, pipe wrenches, screwdrivers, snips, and other construction tools.
This glossary of woodworking lists a number of specialized terms and concepts used in woodworking, carpentry, and related disciplines.
Locking pliers are pliers that can be locked into position, using an "over-center" cam action. Locking pliers are available with many different jaw styles, such as needle-nose pliers, wrenches, clamps and various shapes to fix metal parts for welding. They also come in many sizes.
Slip joint pliers are pliers whose pivot point or fulcrum can be moved to increase the size range of their jaws. Most slip joint pliers use a mechanism that allows sliding the pivot point into one of several positions when the pliers are fully opened.
Channellock is an American company that produces hand tools. It is best known for its pliers—the company manufactures more than 75 types and sizes of pliers—particularly its eponymous style of tongue-and-groove, slip-joint pliers. Its pliers have distinctive sky-blue handle grips; the company has been using the same trademarked shade of blue since 1956.
Crescent is a brand of hand tools. It originated with the Crescent Tool Company, founded in 1907. The Crescent brand has changed ownership multiple times. It is currently owned by Apex Tool Group, LLC of Sparks, Maryland as part of its Hand Tools division. It is best known for its style of adjustable wrench.
A woodworking vise is a type of vise adapted to the various needs of woodworkers and woodworking. Several types have evolved to meet differing primary functions, falling under the general categories of front and end vises, reflecting their positions on a workbench.
