Using this screwdriver set is easy. First, find the right screwdriver with the help of the color - coded tool finder. Then, hold the ergonomic handle firmly. Place the blade on the screw head and turn. The short arm gives you more leverage, so you can apply more force. When not in use, keep the set in a dry place to prevent the blades from getting rusty. Avoid using excessive force that could damage the blades. Periodically clean the blades with a dry cloth to maintain their performance.
