These forged, heavy-duty wire strippers have shear-cutting knives for a lower force to cut copper wire and larger cable such as Romex and other nonmetallic (type NM) cable. Updated design features six stripping holes for 8-18 AWG solid and 10-20 AWG stranded wire. The large knurled plier head pulls and twists wire. Screw shearing holes handle 6-32 and 8-32 screws.
