Abstract
A cutting tool having first and second lever arms with a cutting end and a handle end. A first insert and a second insert are connected to the cutting ends of each of the lever arms. The inserts are removable from the cutting ends of the lever arms, and each of the inserts include multiple cutting edges. When the inserts are connected to the cutting ends of the lever arms and the user pulls the handle ends towards each other, the cutting ends also move toward each other. As the cutting ends move toward each other, the inserts act cooperatively to sever materials located therebetween. When one of the cutting edges of an insert becomes dulled or damaged, the user removes the insert from the cutting end of the lever arm and repositions the insert on the cutting end such that a different cutting edge is revealed for severing materials.
