The joint design reduces the load on the center pin, preventing wear at the pivot point. The protection prevents the operator's fingers from being pinched. Gripping surfaces with specially hardened teeth, tooth hardness approximately 61 HRC for a tool length of 250 mm: low wear and stable grip. Chrome-vanadium electrosteel, forged, oil-hardened. Self-locking on pipes and nuts: no slipping on the workpiece and minimal hand force required.
