In 1933 the first tongue and groove pliers were invented by Channellock, then known as the Champion-DeArmment Tool Company. These specialized
feature jagged jaws that merge into a m angles are set from 45 to 60 degrees from the handles of the tool.
It is believed that the first pincers were invented more than 5000 years ago, around 3000 BC. and that they were most likely originally made of wood. Over time they were made of bronze and later stronger materials such as iron and steel.
This was a breakthrough year for Champion-DeArmment when Chief Engineer Howard Manning developed the concept of a multi-position tongue and groove plier. The pliers were given the name “Channellock” and a patent and trademark protection was granted in 1935.
The first linesman tongs were made 1857 by Mathias Klein, a German immigrant in Chicago. A telegraph operator brought broken side cutters to Klein’s forge.
These adjustable pliers are designed to be used as a hand vise or clamp that firmly locks onto a workpiece. Also known as pliers wrenches, lever pliers and under the brand name Vicegrips, they have a double lever effect.
Klein Tools was founded in 1857 by a hardworking German immigrant, Mathias Klein, who started out in the hand tool shop when a telegraph operator brought broken wire cutters to his forge. Mathias repaired the pliers by forging and finishing a new half for the tool and riveting it to the old half.
In 1933, chief engineer Howard Manning developed the tongue-and-groove slip-joint pliers for which the company is known. A patent was granted for this design in 1934, and a trademark for the name “Channellock” was granted in 1949 with an effective date of May 1, 1932.
Sliding joint pliers are pliers whose pivot or pivot point can be shifted to increase the size range of their jaws. Most slip joint pliers use a mechanism that allows the pivot to be slid to one of several positions when the pliers are fully open.
Tongs are a hand tool used to hold objects in place, possibly developed from tongs used in Bronze Age Europe to handle hot metal.
Adjustable channel locking pliers got the name water pump pliers because they all used to tighten packing nuts on the same.
Klein Tools was founded in 1857 in Chicago, Illinois by German immigrant Mathias Klein. The first tool Klein made was a pair of side cutters for a telegraph lineman.
These New England needle nose pliers from Klein Tools Lineman are made from USA-made forged steel with induction-hardened blades. Their streamlined design with “hand shape” handles also has a unique grip hardening that helps absorb “snapping” when cutting. They have grippy jaws with crosshatched knurling.
Lineman’s pliers (US English), Kleins (generated mark, US usage), Linesman’s Pliers (Canadian English), Side Cutting Linesman’s Pliers and Combination Pliers (UK/US English) are a type of pliers used by plumbers, electricians and other tradespeople primarily for gripping, twisting, bending and cutting wires, cables and…
William Petersen was a Danish immigrant who invented the first locking pliers in his forge and began selling them from the trunk of his car to farmers and people in the surrounding towns. He patented his new idea and called it Vise-Grip.
