Featuring smooth gripping jaws and semi-flush cutting edges, the mini pliers in this set are designed to safely grasp soft metals and delicate parts, and cut soft wire sizes 14-38 AWG. Gently assisting the opening action of pliers, the long arm coil spring is neatly tucked between handles so it won't get in the way or be accidentally dislodged. The spring itself has a relaxed opening angle of 137 degrees-nearly twice the opening angle of the pliers-so it stays properly tensioned when pliers are fully opened. Coiled twice, it achieves the right balance of the force required to open pliers with that required to close them, greatly improving overall control and reducing hand fatigue.
