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. Box joint design allows for a long life and zero backlash. 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 5/64" for soft wire, 1/16" for medium and up to 1/32" 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.
