Use The Right Pliers Pliers today are made for gripping, cutting, crimping, electrical work or other specific purposes. Use pliers designed for the work you are doing. For example, do not try to grip materials with cutting pliers. Not a Hammer Do not use pliers as a blunt force object to hit nails, wood or any other materials. This may damage the tool and make it unsafe for use. Not A Wrench Do not use pliers to fasten or unfasten nuts, bolts or screws. This will damage the tool, and a wrench will minimize stripping. Maintenance Maintain the hinge of your pliers with oil to extend the life of your tool, and ensure proper and safe functioning. Eye Protection Wear safety glasses or goggles especially when cutting wire, metals or other potentially dangerous materials. Source: ehow.com
