After that, the grip width of the pliers is fixed and can only be adjusted by pressing the button. To reactivate the sliding function, the pivot pin is released by pressing the button, and the pliers are fully opened once. Made of chrome-vanadium electric steel, forged, and multi-stage oil-hardened.
