What type of pliers have curved jaws?

Curved-nose pliers are specifically designed with jaws that curve, allowing for more accessibility and reach in tight or awkward spaces. The curvature of the jaws creates a better grip on objects and enables the user to manipulate materials more effectively in confined areas. This design is particularly useful for intricate work, such as jewelry making or electrical tasks, where precision and control are crucial.

In contrast, needle-nose pliers have long, straight jaws that taper to a point, making them ideal for precision tasks but not suited for curved gripping. Cutting pliers are typically designed with sharp edges for cutting wires and do not have curved jaws. Slip-joint pliers feature adjustable jaws that can grip various sizes of objects, but they are not specifically designed with a curve in their gripping surfaces. Thus, the unique design of curved-nose pliers is what makes them the correct answer for this question.
