Using the Honey Badger hook knife is a breeze. To open it, just hold the handle firmly and use your thumb to flick the blade open with the help of the ball - bearing pivot system. When closing, make sure your fingers are clear of the blade path and gently push the blade back in. As for safety, always keep the blade away from your body and others when using or carrying it. Also, don't use it for tasks it's not designed for to avoid blade damage. For maintenance, after each use, wipe the blade with a dry cloth. If it gets wet, dry it thoroughly to prevent rust. You can also apply a thin layer of lubricant to the pivot point every few months to keep the opening and closing action smooth.
