The 450 is an ultra precise needle nose plier capable of grasping and holding wire less than 1 mil thick with the strength for wire forming. Leads "popping" free, tip misalignment and blade crossover will be a memory once you switch to our Tweezer Nose™ pliers. Radiused edges protect lead wires. Light weight and our patented, non-protruding, Light Touch™ return spring help ensure operator comfort
