The knives are heavy duty induction hardened steel that can cut ACSR, screws, nails, and most hardened wire. Their high-leverage design allows for them to have 36-percent greater cutting power than other similar plier designs. Features: Durable molded insulation meets or exceeds ASTM F1505-16 and IEC 60900:2018 standards for insulated tools; Clearly marked with the official 1000-volt rating symbol; Flame retardant, impact-resistant, bright orange outer coating with two layers of insulation provide protection against electric shock; Heavy-duty, induction hardened cutting knives cut ACSR, screws, nails, and most hardened wire; Thick, exceptionally tough, high-dielectric white inner coating is bonded to the tool; High-leverage design for 36-percent greater cutting power than other plier designs; Hot-riveted joint for smooth action and no handle wobble; Forged steel for maximum durability; Flame Retardant and Impact Resistant Handle; Pliers grips made of durable molded insulation meet or exceed ASTM F1505-16 and IEC 60900:2018 standards for insulated tools; Made in USA; Pliers grips made of durable molded insulation meet or exceed ASTM F1505-16(2021) and IEC 60900:2018 standards for insulated tools - Warnings: Only use tools that are marked with the official international 1000-volt rating symbol shown above, if there is any chance that the tools will make contact with an energized source.; Whenever possible, always de-energize lines and equipment prior to working on or around them. Klein insulated tools are designed only to reduce the chance of injury where the tool may make contact with an energized source.; Do NOT touch uninsulated portion of the tool or any conductive object when either might contact an energized source.; Wear approved eye protection.; Always inspect your tools before use. Destroy tool if insulation becomes damaged in any way.; Because moisture, films, or other surface contaminants are conductive, Klein insulated tools must be kept clean, dry, and free of any surface contaminants.
