Using your Deejo knife is a breeze. To open it, simply push the liner lock and unfold the blade. It's great for various tasks like cutting ropes, opening packages, or even preparing small items in the outdoors. When closing, make sure to hold the handle firmly and gently push the blade back in until the liner lock clicks into place. Here are some important notes. Keep the knife away from children. Avoid using it for heavy - duty tasks that could damage the blade. For maintenance, after each use, wipe the blade with a dry cloth to remove any moisture or debris. If it gets dirty, you can clean it with mild soap and water, then dry it thoroughly. Occasionally, apply a small amount of lubricant to the pivot point to keep it working smoothly.
