With a clamshell-like design, Knipex's cable stripping tool cuts and removes the jacket off of CAT5, CAT6 or CAT7 UTP and STP cables with diameters between 4.5 and 10 millimeters. Just place a cable into the central channel, then squeeze and pull. It also includes six supplemental strippers for wires between 24 and 12 AWG (0.2 to 4.0 square millimeters).
