You can recognize the meaning of 'Zange' (pliers/claw) from the context. If it is about crafts or repairs, it refers to the tool. In connection with animals such as crabs or scorpions, it means their grasping tools or pincers. The expression 'in die Zange nehmen' (to put pressure on someone) is purely figurative.
Für diese feine Arbeit brauchst du eine spezielle Zange.
For this delicate work, you need special pliers.
When 'Zange' (pliers) is meant as a tool, it is often used with verbs like 'benutzen' (to use), 'greifen' (to grip), 'halten' (to hold), or 'ziehen' (to pull). You use the pliers to do something.
Er benutzte eine Zange, um den Draht zu biegen.
He used pliers to bend the wire.
The idiom is 'jemanden in die Zange nehmen' (to put pressure on someone). The person who is being put under pressure is always in the accusative.

'die Schere' and 'die Zange' are both tools with two movable parts. That makes them easy to confuse. 'Die Schere' is used mainly for cutting, for example paper, fabric, or hair. 'Die Zange' is used more for gripping, holding, or bending; some pliers can also cut wire. When two blades directly separate material, 'die Schere' is usually meant. When you need to grip or hold something, 'die Zange' is a better fit.
