Launce Barber and Tom Stokes designed the patented Zilla-Tool as part of our innovative I.D. Works line of tools. It really is the monster tool, with a comfortable ergonomic handle that lets you get a lot of work done. The pliers jaws are spring loaded, with a slight needle nose taper. They have both fine flat and circular toothed gripping surfaces. Near the base of the pliers, is a very useful wire cutter and also a notch near the handle for wire stripping. You can store the two screwdriver hex bits in the Zilla-Tool's handle reliefs. It also accepts other standard hex bits. To open the knife blade quickly, just press the little "flipper." It also acts as a blade guard when the blade is open. Metallic surfaces are bead-blast, while the Zilla-Tool's rugged scales are injection molded black glass filled nylon.
