Tools are essential for many jobs, and saws and screwdrivers are two of the most commonly used TOOLS. Saws and screwdrivers are both hand-held TOOLS that are used to cut or shape materials, such as wood, metal, and plastic. Saws are used to make straight or curved cuts in materials, while screwdrivers are used to drive screws into materials. Both saws and screwdrivers come in a variety of sizes and shapes, allowing them to be used for a wide range of tasks.
