A rotary cutter is a tool used primarily for cutting fabric, paper, or other materials. It features a circular blade that rotates as it moves across the surface, allowing for smooth and precise cuts. This tool is popular among quilters and crafters because it can cut multiple layers of fabric at once, saving time and effort. To use a rotary cutter safely, it is often paired with a cutting mat to protect surfaces and prolong the blade's sharpness. Many users also utilize a ruler to guide their cuts, ensuring straight lines and accurate measurements. Proper handling and storage are essential to maintain the cutter's effectiveness and safety.
