Ball Bearing Knife Technology
Ball bearing knives are designed for smooth and efficient opening with a reduction in friction for rapid blade deployment.
A Liner Lock is a folding knife that locks open via a tensioned metal liner inside the handle. Similar to a Lockback, opening the blade activates the lock. Unlocking is achieved by placing the thumb on the front part of the liner and pushing to the left, which releases the blade. Liner locks are typically one hand open, one hand close. A blade thumbstud, flipper, or hole, enables one hand opening.
