As an entry in the experimental Project ATOM series, the Inverse is a Kershaw like no other. This fixed blade has a blunt edge and no blade steel. It's made with a strong PA-66 nylon and glass fiber combo material. The mini-sized fixed blade is fun to show off to friends and easy to carry. At an ultralightweight of 0.4 ounces, the Inverse is almost unnoticeable when it's not being used. In a last resort emergency, the sharp tip can be used as a self-defense mechanism. An attractive steel overlay adds an extra layer of detail to this new, exciting knife from Kershaw.
