The Airlock is part of Kershaw’s Starter series, designed to provide more style and more advanced features—for less money. For style, the Airlock has a slim, speedy look with a distinctive cutout in the handle that mirrors the handle shape. This “airlock” lets you see through to the stainless steel liners. A Decorative pivot works with the handle machining for an integrated look. The reversible pocketclip looks like a pen clip and helps the Airlock almost disappear in your pocket.
