The Kershaw Natrix series is characterized by its patented sub frame lock mechanism, in which one side of the handle has a steel plate for secure lockup, while the rest of the handle can be made from other materials. On this version, the handle is constructed from solid copper, the blade from D2 steel. Machined holes on both sides allow you to position the clip on either side, too. Featuring a 2.75-inch drop-point blade, the Natrix is versatile enough for slicing, piercing, chopping, and more. Flip it open with a press on the flipper tab. Thanks to the sub frame lock construction, the knife weighs just over 3.5 ounces despite its 6.5-inch-long body.
