If you're a handy homeowner, it's likely that you have a screwdriver as part of your essentials. They are definitely necessary to have around; this is because they can fix so many damaged items like loose handles or screws that don't really seem to want to stay put. If you don't own one, we highly recommend running to the hardware store so that you won't have to borrow from your neighbors.
Screwdrivers come in a variety of sizes, but having a complete kit is a brilliant idea. Just in case you end up needing a specific type of head for a certain project.
