What is the main advantage of using a utility knife over other cutting tools for drywall?

1. It cuts faster

2. It is more expensive

3. It provides greater precision

4. It is heavier

The correct answer is: It provides greater precision

Using a utility knife for cutting drywall offers the primary advantage of providing greater precision compared to other cutting tools. The design of a utility knife allows for controlled cuts, enabling the user to easily follow lines and achieve accurate measurements. This precision is particularly important in drywall installation, where fitting seams and corners snugly can affect the overall appearance and structural integrity of the finished work. Utility knives are lightweight and generally easy to handle, giving the user better maneuverability to make intricate cuts, such as those required when trimming edges or cutting out openings for outlets. The blade can also be easily replaced or sharpened, ensuring that the tool maintains its cutting effectiveness for precise work. Other cutting tools may be faster or heavier, but they often sacrifice the level of control and accuracy that a utility knife provides, making it a preferred choice among professionals in interior systems who prioritize precision in their workmanship.
