Parrot 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.

A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal, or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship.
An adjustable spanner, also called a shifting spanner 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. The first permanent settlement in Northwestern Pennsylvania, Meadville is within 40 miles (64 km) of Erie and within 90 miles (140 km) of Pittsburgh. It is the principal city of the Meadville micropolitan area, as well as part of the larger Erie–Meadville combined statistical area.
A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from other metals, by forging the metal, using tools to hammer, bend, and cut. Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was a historical distinction between the heavy work of the blacksmith and the more delicate operations of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is variously called a smithy, a forge, or a blacksmith's shop.
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 linear dimensions of an object or hole; namely, the length, width, thickness, diameter or depth of an object or hole. The word "caliper" comes from a corrupt form of caliber.
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.
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. The jaws are often flat but may have grooves, adapt to the shape of the workpiece or be custom made.
Knipex is a globally-distributed German manufacturer of hand tools, best known for its pliers. Knipex tools are principally used by professionals in various trades but find increasing popularity in DIY and EDC markets.
The Woodwright's Shop was an American traditional woodworking show hosted by master carpenter Roy Underhill and airing on television network PBS. It is one of the longest running how-to shows on PBS, with 36 13-episode seasons produced. The show debuted as a local program in 1979, and the show went national in 1980. It is filmed at the UNC-TV studios in Research Triangle Park, North Carolina. It is no longer being produced.
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.
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.
