New head design to increase durability and cutting capacity Cutting edges designed to cleanly cut all types of wire: soft wires and modern materials to a maximum piano wire specification of: - 192A.16CPE : 2.0mm 210 kg/mm² - 192A.18CPE : 2.2mm 205 kg/mm² - 192A.20CPE : 2.5mm 200 kg/mm² High Mechanical advantage due to off-set rivet and cutting edge geometry reducing effort. High durability Carbon alloy steel, with induction hardened cutting edges. Bi-Material ergonomic grips resistant to chemical agents featuring: - Return spring - Tether ready point (Tether point adds 10mm to nominal lenght) Chrome finish for corrosion resistance
