Using your Deejo knife is easy. To open it, simply press the liner lock and unfold the blade. You can use it for various tasks like cutting ropes or opening packages. When carrying it, use the belt clip to attach it to your belt. For safety, always make sure the liner lock is engaged when the blade is open. When not in use, keep the knife closed to avoid any accidental cuts. To maintain your knife, clean it with a dry cloth after each use. If it gets dirty, you can wash it with mild soap and water, then dry it thoroughly. This will keep your knife in good condition and ready for your next adventure.
