Which tool is most commonly used to cut drywall?

1. Jigsaw

2. Utility knife

3. Reciprocating saw

4. Table saw

The correct answer is: Utility knife

The utility knife is the most commonly used tool for cutting drywall because it is specifically designed for this purpose. The blade of a utility knife enables precise and clean cuts, making it ideal for the thin, layered structure of drywall sheets. It allows the user to score the surface of the drywall easily, after which the sheet can be snapped along the scored line. This method minimizes damage to the paper facing of the drywall and provides a clean edge, which is essential for achieving a professional finish. Other tools, while they can be used for cutting drywall, may not offer the same level of control or precision. For example, a jigsaw is generally used for more intricate cuts or curves; a reciprocating saw is typically reserved for demolition work or cutting through thicker materials; and a table saw is designed for making straight cuts in larger wood pieces rather than drywall sheets.
