Cold Steel Training Swords
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 Weapons 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.
The Cold Steel Sword Breaker Trainer has a striking square cross section and molded hollow ground "flats".
