The following information is taken from Gerber's web site:
We can think of about 600 reasons why this much-applauded multi-tool belongs on your belt. But don't worry, well just stick to the most important ones here. Like profound versatility, for example. And fail safe performance. And a level of rock-solid design and construction that pleases the eye and satisfies the soul.
It all begins with high quality stainless steel. Then we incorporated Gerber's patented one-handed opening pliers. Top that off with our patented replaceable tungsten carbide wire cutters. When the cutters become dull or misshapen simply rotate the tungsten carbide cutters 120-degrees, and you've got yourself a good-as-new wire cutter. After three rotations, the entire cutter can be replaced.
You'd be hard pressed to find a more rugged or more fearless multi-tool out there. But go ahead and look around a bit. See what you think. Then come on back to Gerber and pick the Multi-Plier 600 that truly suits your needs. We're building plenty. The ballistic nylon sheath is part of the package.
