Using the Klein Tools K28 screwdriver is a breeze. First, wedge the split - blade tip into the slot of the slotted screw. This will securely hold the screw in place. Then, you can start driving the screw into the desired spot, even in hard - to - reach areas. Just keep in mind that this screwdriver isn't meant for torquing or tightening. When it comes to maintenance, wipe the steel shank and tip with a clean, dry cloth after each use to prevent rust. Store it in a dry place, and if possible, keep it in your toolbox to avoid damage. Since it's not insulated, don't use it for electrical work to stay safe.
