The Kershaw Nura 3.0 and Nura 3.5 Knives are designed by Belarusian knifemaker Dmitry Sinkevich. Each Kershaw Nura Knife has a blade made of 8Cr13MoV stainless steel with a Flipper and the KVT ball bearing sytem for smooth ambidextrous one hand opening, and a slim stainless steel handle with decorative grooves and a frame lock.
From the Kershaw website: ... Nura features Kershaw's KVT ball-bearing system for smooth, easy opening without a mechanical assist. Instead, the user pulls back on a flipper and the blade moves out of the handle quickly and easily. The key is a washer with caged ball bearings that surrounds the pivot and makes opening the knife nearly frictionless.
The Nura handle design has a sleek, streamlined look and feel. The blade is quality stainless steel, heat treated to Kershaw's demanding specifications to bring out the best qualities in the steel, then titanium carbo-nitride coated for additional protection and performance. The slim handle is made of stainless steel with machined grooves that provide style and extra grip. The handle is titanium carbo-nitride coated, then sanded to reveal a shiny steel surface. A frame lock provides blade lockup security.
