The type of pliers that can be adjusted to various jaw openings by turning the knurled adjusting screw at the end of the handle is known as Vise Grip pliers. This design allows the user to lock the pliers in place at a desired jaw width for gripping various sizes of objects, which enhances versatility in gripping and clamping tasks. The mechanism of the adjusting screw provides a quick and reliable way to customize the jaw opening, making Vise Grip pliers especially useful for applications where a secure grip on different sized workpieces is needed.

In contrast, other types of pliers, such as slip joint pliers, have a predetermined adjustment that allows for limited jaw size changes based on the specific grooves in the pivots. Needle nose pliers are designed for precision and fine work but do not offer adjustable jaws. Channel lock pliers, also known as groove joint pliers, allow for adjustable jaw openings but typically rely on a series of grooves rather than an adjusting screw mechanism. Thus, the design and functionality of Vise Grip pliers distinctly sets them apart in this context.
