Using these Klein D252-6 diagonal-cutting pliers is easy. Just grip the plastic-dipped handles comfortably and place the wire between the short jaws. The beveled cutting edges will help you make a clean cut, especially in tight spots thanks to the tapered nose. When using, avoid cutting materials harder than what the pliers are designed for to prevent damage to the cutting knives. For maintenance, keep the pliers clean and dry. You can wipe them down with a dry cloth after each use. If they get dirty, you can use a mild cleaner. Store them in a dry place to prevent rusting. With proper use and care, these pliers will serve you well for a long time.
