Cold Steel says their Voyagers® are, ounce for ounce, far stronger than 99.9% of the competitor's folders. And this is a fact, not an idle boast. Each knife features precision made parts with a stiff spring and our incomparable Tri-Ad® lock mechanism which is arguably the strongest, most reliable, low maintenance lock in the world! The thick, extra wide blades are made from Carpenter CTS® BD1 Alloy steel and meticulously ground to a thin edge for maximum shearing potential. This thin edge also allows each blade to be honed to an astounding sharpness. And, because of the high carbon content of the steel, and their near perfect heat treatment, you'll find this sharpness last a surprisingly long time. . The Voyager® Series also offers all the other latest refinements in lock-back construction including lightning quick, one-handed opening, state of the art mechanical fasteners, massively oversized pivot pins that are fully adjustable and properly hardened, and dual stainless steel pocket clips for ambidextrous carry and deployment. The Griv-Ex handles feature 6061 heat treated aluminum liners for the utmost in strength and stiffness and are ergonomically designed to afford a wide array of grip options including the palm reinforced forward grip for which they are particularly well suited. Griv-Ex is unparalleled as a handle material as it is considerably stronger than Zy-Ex and, when deeply textured, offers a terrific non-slip grip. As an added bonus, it's impervious to moisture and won't crack, warp or shrink and remains remarkably resistant to abrasion or discoloration. As tools these lightweight, super sharp knives are appropriate in almost any environment from hunting and camping to hiking and general utility chores. They can also readily fill specialty functions such as a boat or river knife, chute knife or police/military and survival/rescue applications.
