Using this Klein Tools screwdriver set is easy. First, use the Tip - Ident® feature to quickly identify the right screwdriver for your screw. Once you've selected the correct one, hold the screwdriver by the Cushion - Grip handle for maximum comfort and torque. Place the tip precisely on the screw and turn it to either tighten or loosen. When using, make sure not to apply excessive force that could damage the tip or the screw. After use, wipe the screwdrivers clean with a dry cloth to remove any dirt or debris. Store them in a dry place to prevent corrosion. Check the blade anchor regularly to ensure it remains solid. With proper care, this screwdriver set will serve you well for a long time.
