When it comes to screwdrivers, there are two points of focus: tip and grip. You'll want a couple of different kinds of screwdrivers, each sporting the most popular (re: useful) types of tips. A Phillips-head screwdriver features a cross-shaped metal tip that corresponds with the cross-shaped depression in the most popular type of screw. You'll also want a flathead screwdriver, also known as slot head screwdriver. This jack-of-all-trades screwdriver is designed to fit traditional screws with a single, linear depression. And because of its wedge-style tip, it's also good for prying or scraping.
Whatever the head, choose a screwdriver with a cushioned, textured grip. This will help you torque tight screws. And consider buying a few flathead and Phillips-head screwdrivers in a variety of handle lengths. You may not use the shortest handle lengths often, but when you need to fit in a tight space, you'll be glad they're in your arsenal [source: McKay].
