They are useful for cutting the ends of plastic zip ties. Conventional wire cutters leave razor-sharp edges when cutting through plastic cable ties. These Whizzotechs make for a nice, clean, flush cut when held perfectly parallel to the plastic binding head. However, they are about half the weight and half the strength of my favorite Stanley 84-135 pliers. Stanley pliers are almost impossible. is found these days, so Whizzo is a good second choice.
