Using your Klein Tools 32398 screwdriver set is easy. Just pick the right screwdriver for the job, and insert the tip into the screw head. Apply a bit of pressure and turn it to loosen or tighten the screw. The Cushion - Grip handle gives you a good hold and makes it more comfortable to use. When you're done, store the screwdrivers in a dry place to prevent rust. Don't use them on screws that are too big or too hard for the screwdriver's size, as this could damage the tip. If the tip gets dirty, you can clean it with a soft cloth. And if you need to replace a bit, you've got a spare in the set.
