The Madrock is a slip-joint knife (blade does not lock, but is instead held by a spring, which allows the blade to fold when a certain level of pressure is applied). Design upgrades include: same blade length as the original World Legal yet with a shorter overall length and reduced weight for an enhanced everyday carry experience, and an inwardly curving blade. The handle features a low-profile deep pocket clip and a tactile rubberized grip that resists slipping even when wet.
