The opening mechanism is innovative and futuristic. Nudge the upper crossbar with your thumb—while the rest of your fingers firmly grasp the handle, and the blade slides open and locks in place. Shift the discrete lever at the base of the finger loop and the blade retreats into its closed position. The pocket clip is also a first, sitting almost completely flush with the handle and likewise activated with light thumb pressure. You will love the challenge and the practice it takes to operate the knife smoothly. Once practiced, it is impressive.
