Using your Deejo knife is a breeze. To open it, just use one hand to flick the blade open and the liner lock system will keep it securely in place. You can use the half - serrated blade for various tasks, like cutting ropes or slicing through food. When you're done, simply push the liner lock to release the blade and close it. As for carrying, clip it onto your belt using the built - in belt clip. When it comes to maintenance, clean the blade with a dry cloth after each use to prevent rust. Avoid exposing the coral wood handle to excessive moisture as it may damage the wood. Store your knife in a dry place, and it will serve you well for a long time.
