Using the Oyo Kasteoksa double - bladed throwing axe is easy. First, hold the axe firmly by the shaft. Make sure you have a clear and safe throwing area. Step back a few feet and then with a smooth motion, throw the axe towards the target. Remember, practice makes perfect, so keep at it to improve your aim. As for safety, this axe is heavy, so it's not for children or light - weighted people. Always wear appropriate safety gear like goggles when throwing. When it comes to maintenance, after each use, wipe the blade clean with a dry cloth to prevent rust. Keep the leather protector on the blade when not in use to protect it. Store the axe in a dry place to ensure its longevity.
