The CRKT® SeismicTM Knife is a simple yet incredibly-strong everyday carry solution. This folder combines FAST one-handed opening with super-easy closing thanks to the IKBS ball bearing pivot with Deadbolt locking mechanism. With one push of the flipper, the blade swings out almost effortlessly and locks solidly into place with a steel bolt. One push of the button on the opposite side disengages the lock and allows easy one-handed folding back into the closed position. Veff Serrations cut easily through tough nylon and fiber materials.
