Abstract: A set of pliers for easily and quickly removing concentric or standard knockouts from steel outlet boxes and the like. The subject tool is a set of pliers, comprising a first arm having a first end and second end and a second arm having a first end and second end, where the first arm and the second arm are pivotally connected with respect to one another by an interconnecting mechanism located between the first and second ends thereof. The first arm forms a first jaw located above the interconnecting mechanism of the first arm and the second arm forms an opposing, second jaw located above the interconnecting mechanism. The first jaw includes a first projection that extends from an area between the first end of the first arm and the interconnecting mechanism. The second jaw includes a second projection that extends from the end of the second arm. The first projection abuts the second jaw and the second projection abuts the first jaw. Thus, the first and second projections do not touch.
