Abstract: A joint of a pair of channel-lock pliers having an adjustable handle and a reference handle that are pivotally connected at a junction includes an elongated hole defined through the reference handle at the junction, a joint hole defined through the adjustable handle at the junction corresponding to the elongated hole and a pivot pin pivotally connecting the adjustable and the reference handles at the junction. The pivot pin has an enlarged first end and a second end, which passes through the elongated hole and the countersunk pivot hole in the handles and extends out of the countersunk pivot hole in the adjustable handle to be pressed and spread to pivotally rivet the handles together and be ground smooth to prevent protruding from the adjustable handle. Consequently, the handles are joined firmly, and appearance of the pliers is nice.
