Using this Deejo knife is a breeze. To open it, simply use your thumb to release the liner lock and unfold the blade. When you're done, close it carefully by pressing the liner lock and folding the blade back in. As for the belt clip, you can easily attach it to your belt for convenient carrying. When using the knife, always keep your fingers away from the blade to avoid cuts. Don't use it to cut extremely hard materials like metal, as this could damage the blade. For maintenance, clean the blade with a soft cloth after each use. You can use a mild soap and water if it's dirty, but make sure to dry it thoroughly to prevent rust. Periodically, apply a small amount of knife oil to the blade to keep it in good condition. The olive wood handle can be wiped clean with a dry cloth. Avoid exposing the knife to extreme heat or cold, as this could affect the integrity of the materials.
