Forged from high-grade chrome vanadium electric steel and oil-hardened, they have a black atramentized finish and are available with non-slip plastic or multi-grip handles. Knipex TwinGrip slip joint pliers are designed with a 3-point system (three contact points within the jaw) for reliable gripping of flat workpieces.
