The Knipex 6-1/4" X-Cut Insulated Compact Diagonal Cutters (7306160) require 40 percent less forced than other diagonal cutters due to its large opening and double-supported joint axis that allows the user to perform heavy duty cutting with minimal effort. They are able to cut the finest strands, even copper wires, as well as multi-core cables and piano wires. These cutters are insulated for 1000V, compact and durable, forged from chrome vanadium steel and oil hardened for long life.
