Channellock

Channellock is an American company that produces hand tools. It is best known for its pliers—the company manufactures more than 120 types of pliers—particularly its eponymous style of tongue-and-groove, slip-joint pliers. Its pliers have distinctive blue grips; the company has been using the same trademarked shade of blue since 1956. It also produces cutting pliers, linemen's pliers, long nose pliers, adjustable wrenches, screwdrivers, nutdrivers and special purpose pliers, as well as multi-function tools for the fire service and other first responders. All of its pliers are manufactured at one of its two facilities in Meadville, Pennsylvania.
