## At a glance

- Slim-forged construction is described as lighter than traditional forged wire strippers.
- Designed to strip 12-14 AWG solid, 14-16 AWG stranded and 12/2 or 14/2 NM-B wire.
- Built-in spring opens the handles after use, while the shear cutter also cuts specified machine screws.
- Cross-hatched jaws are claimed to grip and twist up to three 12 AWG wires.

## Pros

- Combines wire stripping, cutting, gripping and twisting functions in one hand tool.
- The internal spring is intended to reduce repeated manual handle opening.
- The listed stripping ranges make its supported wire applications clear.

## Cons

- The listed stripping capacities cover only the stated wire and NM-B sizes, so buyers needing other gauges may need another tool.
