The RJ I is a RJ Martin designed knife that features Kershaw's SpeedSafe assisted opening mechanism that quickly deploys the blade with a push of the flipper or thumbstud. The RJ 1 blade design and grind provides a slight curved belly and a flat-ground tanto tip that is significantly thicker than comparable tantos. The result is an über-strong tip that takes on the toughest piercing tasks with no fear. The RJ I features 3-D machined G-10 handles with a stainless-steel liner lock on the back only, making it a lightweight carry. Carries tip-up or tip-down for right-handers and tip-up for lefties.
