Kershaw Natrix with D2 steel and Copper handle. The Kershaw Natrix is based on brother brand Zero Tolerances 0770, which itself was inspired by the award-winning ZT 0777. Like other Natrixes, this one features a drop-point blade that offers solid performance. But it also offers upgraded D2 blade steel. This high-carbon tool steel is highly wear resistant, tough, and offers excellent edge retention. The stonewashed finish on the blade goes perfectly with its intriguing copper handles. Yes, copper. Since copper is denser than stainless steel, this smaller knife has some heft. And a lot of style, too. You'll especially like the look once the handles have earned some patina. Accessed with the built-in flipper, Kershaws KVT ball-bearing opening makes it easy to open the knife one-handed. An oversized pivot provides an attention-grabbing detail on the front of the knife, while our patented Sub-Frame Lock secures the blade and provides a dramatic, contrasting line on the back. A decorative backspacer adds another embellishment. And finally, a custom-designed deep-carry pocketclip echoes the lines of a special recess machined into the handle to complete this good-looking knife. With it's smaller size and eye-catching copper handles, the copper Natrix makes a perfect EDC.
