Using this knife is a breeze. Just open it up using the liner lock system. You can carry it around easily thanks to the belt clip. When using, make sure to keep your fingers away from the blade to avoid cuts. For maintenance, wipe the blade with a dry cloth after each use to prevent rust. Store it in a dry place. If the blade gets dull over time, you can use a knife sharpener to bring back its edge. Don't use it for tasks it's not designed for, like prying open cans, as it could damage the blade or the handle.
