What tool would be the last resort when no better options for holding a device are available?

Adjustable pliers are commonly considered a last resort tool when no better options for holding a device are available because they can grip a variety of shapes and sizes due to their adjustable jaws. They are versatile and provide a strong gripping force, which is particularly useful in situations where specific holding tools may not fit or are unavailable. Using adjustable pliers allows you to secure an object tightly, though they may not be the ideal choice for precision work. Their design allows for quick adjustments, making them adaptable to various applications. However, it’s important to recognize that they can potentially damage the surface of the object being held, which makes their use optimal primarily in scenarios where other, more specialized tools are not available.
