How do I know what type of screwdriver set I need?

Screwdriver sets come in different styles for different purposes. If you're working on jewelry or electronics, for example, a jeweler's, precision or mini screwdriver set has the fine tips you need to get into the grooves of the tiniest screws. For standard household or mechanic use, a standard flathead, Phillips head, magnetic or ratcheting set has larger tips that fit into bigger screw heads.

What are the advantages of magnetic and ratcheting screwdriver sets?

Screwdrivers with magnetic tips hold onto the screws you remove until you manually pull them off the end of the driver. Ratcheting screwdrivers let you use one handle and your choice of bits from the set. A gear, pawl and mount assembly inside the handle of ratchets help you tighten or loosen the screw. This relieves stress on your hands when you have a big job, and it exerts more torque when you're removing or inserting screws that are resistant to turning.
