For fine cutting work in electronics and find mechanics. All edges are smooth - less damage to surrounding components. Low-friction double spring for gentle and even opening of the pliers. The bolted joint provides the most precision and a permanently even cutting movement making it a perfect fit for repetitive type applications.. Great for general purpose cutting of wire and components. Cutting edge hardness (approx. 60 HRC) for longer life and for more durable cutting. Cutting capacity - up to 1/16" for soft wire, 3/64" for medium and up to 1/64" for hard wire. The mirror polish together with a fine film of oil offer effective rust protection - no circuit faults caused by peeling chrome from plated tools. ESD (electrostatic discharge) handles discharge electrostatic energy through the handles in a gradual and controlled manner which protects components endangered by electrostatic discharge.
