A pair of locking pliers includes a first grip structure including a first jaw and an adjustment screw connected to a first handle. A second grip structure cooperates with the first grip structure. The second grip includes a second jaw pivotally connected to the first handle about a first pivot axis and a second handle pivotally connected to the second jaw about a second pivot axis. A lock mechanism is pivotally connected to the second handle about a third pivot axis. The lock mechanism abuts the adjustment screw which restrains the lock mechanism to the first handle. The second handle extends longitudinally and terminates at an end at a first length from the second pivot axis. A second length measures a distance between the second and third pivot axes. The second length is smaller than 0.19 times of the first length.
