Sixth-generation family employee Ryan DeArment holds a billet of C1080 alloy steel where all Channellock tools get their start.
The machine hammers out the parts with nine tons of pressure while bouncing the ground floor of the factory like a continuous earthquake.
The parts are diverted into bins by the lower conveyer belt while the scrap metal rides the upper belt into a large hopper to cool.
The angled grooves in these tongue and groove pliers would be impossible to form with a forging process.
After milling the joint surfaces and shaping the cutting edges, the two halves of a tool are riveted together and the rivet is ground flush as shown on these diagonal cutters.
Pliers' thin cutting edges are laser-hardened (a process I wasn't allowed to photograph), but radio frequency hardening is used to harden the entire head of some tools like these nippers.
Skilled "filers"? inspect and adjust the cutting edges and joints of the tools and make fine adjustments by hand if needed.
