Why do my combination pliers have a light gap between the gripping jaws?
Combination pliers have (at least) two functions.
In production, it must be decided which function should have priority in the long term. This priority is given to the cutting function in combination pliers. For the cutting edges there is a distance between them and the gripping area so that nothing will be cut accidentally.
The standard ISO 57 46, which applies to combination pliers, specifies how large this distance may be. KNIPEX complies with these tolerances.
The permissible gripping jaw gap depends on the size and is 0.4 mm for 180 mm long pliers.
