Using this knife is a breeze. Just press the liner lock to open and close the blade safely. When using it, make sure to keep your fingers away from the sharp edge. For daily use, it's great for cutting small items like ropes or opening packages. To keep it in good condition, clean the blade with a dry cloth after each use. Avoid exposing it to harsh chemicals or leaving it in wet conditions for a long time. Once in a while, you can apply a little oil on the blade to prevent rust. Store it in a dry place when not in use, and the belt clip makes it convenient to carry around with you.
