Which tool is designed with handles that lock to hold wire in position?

1. Cable cutters

2. Wire strippers

3. Safety wire pliers

4. Needle nose pliers

The correct answer is: Safety wire pliers

The tool designed with handles that lock to securely hold wire in position is the safety wire pliers. This tool is specifically engineered for the purpose of twisting and securing safety wire, which is a crucial task in various mechanical applications, ensuring that parts stay secured and preventing them from loosening due to vibration or movement. The locking mechanism in the handles allows the user to maintain a consistent grip, making it easier to manipulate the wire and create tight twists without needing to exert constant hand pressure. In contrast, cable cutters are focused on cutting through cables and do not offer a locking mechanism. Wire strippers are intended for removing the insulation from wires without damaging the conductor, and needle nose pliers are designed for gripping and holding small objects but do not have the locking feature that is essential for safety wire tasks.
