The Heavy-Duty Wire Stripper, No. K12055, from Klein Tools is forged from the company’s U.S.-made proprietary steel and four times stronger than traditional Klein wire strippers. The Heavy-Duty Wire Stripper is designed specifically for stripping, cutting and twisting 10-18 AWG solid and 12-20 AWG stranded wire. The stripping holes are precision-ground and the cutting knives are induction-hardened for longer life. Another unique feature is the thicker, knurled jaw that can twist up to three wires at a time. The Heavy-Duty Wire Stripper has a hot-riveted joint designed for smooth action and no handle wobble. It also has 6-32 and 8-32 bolt shearing holes and Klein-Kurve comfort grip handles.
