A wallboard saw is a type of hand saw specifically designed for cutting through wallboards, also known as drywall or plasterboard. It typically has a narrow, pointed blade with small, sharp teeth that are designed to easily cut through the soft gypsum material of the wallboard. The blade of a wallboard saw is usually around 6 to 8 inches long and is attached to a comfortable handle for easy gripping and control. Wallboard saws are commonly used by carpenters, drywall installers, and DIY enthusiasts for making precise cuts in wallboards during construction or renovation projects.
