Using the Klein Tools 671-6 Rapi-Driv Screwdriver is easy. Just hold the Cushion-Grip handle with one hand and use the crank - action to spin the screw in or out quickly. This is great for long - threaded screws in switch plates and light fixtures. When using, make sure the cabinet tip fits well into the screw head to avoid slipping. As it's not magnetic, be careful not to drop the screw. For maintenance, keep it clean. You can wipe it with a dry cloth after each use. Since it's made of steel and chrome - plated, it resists corrosion well, but try to avoid leaving it in a very wet environment. And remember, it's not insulated, so don't use it on live electrical parts. This screwdriver is made in the USA and meets high standards, so it should serve you well for a long time.
