True, only because a bolt cutter is for cutting through solid round shape steel such as a bolt, the shackle on the lock or a link of a chain. To cut cable, they use cable cutter. The blade is different. The bolt cutter is made to smash the steel deforming and flattening it until it gives. A cable cutter is more like a sharp shear. It cut the fine strand of cable individually as force is applied until all strand are cut. Sort of like how a sissor can cut through a rope but cannot cut through a stick such as a chopstick of the same diameter as that rope. In reverse, you can use a hammer to smash through a chopstick but harder to smash through a rope.
