Using your Deejo knife is easy. To open it, simply use your thumb to slide the blade out until the liner lock clicks into place, securing the blade for use. When you're done, press the liner lock to release the blade and fold it back in. For everyday use, this knife is great for tasks like opening packages, cutting ropes, or preparing food during a picnic. When it comes to safety, always keep your fingers away from the blade when opening and closing the knife. Also, make sure to use it on appropriate surfaces to avoid damaging the blade. For maintenance, clean the blade with a soft, dry cloth after each use. If it gets wet, dry it thoroughly to prevent rust. You can also apply a small amount of knife oil to the blade occasionally to keep it in top condition. As for the juniper wood handle, avoid soaking it in water as it can damage the wood. Instead, wipe it gently with a damp cloth if needed.
