High leverage design for superior cutting ability. The curved jaws provide superior holding for a cleaner and more concentric cut. The tool is for cutting aluminum and soft copper and not for use on steel or ACSR type cables. The shear-type jaws cut up to 100-pair cables (24 AWG). The tool has built-in spring and lock for safety. The lock has a unique feature where the lock is released by squeezing handles together. Made of chrome vanadium steel.
