Using this Klein Tools screwdriver is a breeze. Simply select the right screw and align the square - recess tip of the screwdriver with it. Hold the Cushion - Grip handle firmly and turn. The handle is designed to give you more torque, so you won't have to put in too much effort. When using it, make sure to keep it away from water as it's not insulated. Also, don't use it for jobs that require a magnetic tip. For maintenance, after each use, wipe the screwdriver with a clean, dry cloth. The chrome - plated shaft resists corrosion, but it's still a good idea to store it in a dry place to keep it in top condition.
