The Cobra adjusts by pushing a button and sliding the upper jaw, no unhooking, no repositioning the hand. Twenty-five positions across the range, and the jaw sets itself parallel to the work as it closes.

The self-locking geometry is the part that matters: load applied to the handles pulls the jaws further into the work rather than spreading them, so the tool does not slip off a rounded nut the way a channel-lock does. Gripping surfaces are induction-hardened to around 61 HRC.

Box joint construction, forged from chrome vanadium electric steel and oil-hardened.
