Using the Klein 605-4 screwdriver is easy. Just pick the right job for its narrow tip, like working in tight spots. Hold the Cushion-Grip handle firmly to get the most torque and comfort. When you use it, make sure the Tip-Ident® shows the correct orientation for the best fit. For safety, since it's not insulated, don't use it near live electrical wires. To keep it in good shape, wipe it down after each use to prevent dirt buildup. Store it in a dry place to avoid rust, especially because it's made of steel. Check the tip regularly for any signs of wear and tear. If it starts to look dull or damaged, it might be time to replace it.
