<human>:  What is the difference between a Phillips and a flathead screwdriver?
<bot>: The most noticeable difference between a Phillips and a flathead screwdriver is their shape. A Phillips head screwdriver has a cross shaped tip, while a flathead screwdriver has a wide, flat tip. Phillips head screwdrivers are often used in applications where additional torque is necessary, such as when driving screws into hardwood or metal. The flathead is usually used when less torque is necessary, such as when working with plastic, as the wide head prevents slipping and causing damage.
