________ pliers include notches for removing the insulation from wire.

1. Slip-joint

2. Needle-nose

3. Stripping

4. Locking

The correct answer is: Stripping

Stripping pliers are specifically designed for the purpose of removing insulation from electrical wires. They have notches or grooves that are precisely calibrated to cut the insulation without damaging the wire itself underneath. This tool simplifies the process of preparing wire for connections, ensuring that the user can easily expose the necessary amount of wire while maintaining the integrity of the conductor. The design and function of stripping pliers differentiate them from other types of pliers. For instance, slip-joint pliers are variable in their jaw opening and are typically used for gripping and turning objects rather than stripping insulation. Needle-nose pliers excel at reaching into tight spaces and bending wire but do not have specialized notches for stripping. Locking pliers, on the other hand, are used for gripping and holding materials securely but are not intended for wire preparation tasks. Thus, the unique features of stripping pliers, aimed specifically at electrical work, make them the correct choice for this question.
