This concept was implemented by the ancient Romans, who used dull wooden swords to train their Gladiators and soldiers. And Japanese Samurai used a wooden training sword that was called a Bokken. It's an elegant solution to a vexing problem and effective enough to still be used today. The only problem is that a wooden sword can rot, crack, chip or splinter and eventually become useless. Cold Steel's solution to these dilemmas was to design a synthetic substitute, low in price and impervious to the elements. The Cold Steel line of Training Swords are made of heaviest grade polypropylene available and closely duplicate a real sword in length, size, weight and feel. While they're not quite as rigid as wood, they have the winning advantages of being virtually unbreakable, remarkably stiff and cut resistant.
