The Klein Tools Klein-Kurve Shear-Cut, Heavy Duty Wire Stripper 8-20 AWG, No. K12035, is forged from Klein’s U.S.-made, proprietary steel blend, providing four times the strength of traditional Klein wire strippers. The K12035 strips 8-18 AWG solid wire, and 10-20 AWG stranded wire. The large knurled plier head pulls and twists wire, the shear cutting knives provide easier cutting of copper wire and larger materials, and the comfort grip handles have a textured grip for reduced hand fatigue and enhanced dexterity.
