The tool does not exist... I am a plumber and I use it almost daily for everything.. And Knipex warranty of course

Only good words I can say about this strange tool. I bought it after watching some foreign reviews on youtube and I was really surprised by its usefulness. It replaces traditional pliers and is perfect for removing stuck-rusty screws that have become one with the material they are screwed into.

It is suitable for many types of tasks with this head and its narrow lever. It has very good teeth and head design and bites well. Its main advantage is that its opening can be adjusted and it bites equally well and vertically. In addition, its thicker handles help to apply force due to its insulation materials. It also comes with a thinner handle material for narrower areas and better feel-precision in the hand.
