Yep it's easier! Yes Folks, it's true.
You can make Z-Bends using ordinary pliers and the bend and twist method but let me tell you; It is so much easier to make Z-Bends with a set of Z-Bend pliers.
If you look at the above pictures closely you will notice a pin sticking out of the nose on these pliers. That pin gets inserted into the servo control horn (servo and control surface need to be set to their neutral positions 0/0°). Then lightly grip the pushrod in the pliers teeth, remove the plier pin from the servo horn and squeeze. There you go an accurate Z-Bend right where you need it and at the correct angle and length.
One thing to note with these pliers is that when the jaws are fully closed you will notice that one side closes tighter than the other side. This is intentional. The tight side is for bending thinner wires and the open side is for your thicker wire.
For instance if you use the gapped jaws to bend thinner wire, the Z-Bend wont be as tight as it will be if you use the tighter gapped jaw. See the pictures above for more clarity.
