These Knipex High Leverage Lineman’s pliers require 50% less effort thanks to an optimized transmission ratio and ergonomic handle design. They feature a New England Head with cross-hatched knurled jaws for secure gripping, serrated zones for added leverage, and hardened cutting edges (approx. 64 HRC) for tough wire, nails, and even piano wire. Made from forged, oil-hardened vanadium steel, the 09-12-240 model also includes a fish tape puller and universal crimping point for added versatility.
