Scott Ferguson may be a high-school math teacher, but he's also a serious history buff. He brings his passion for studying the greatest medieval and Renaissance swordsmen to his role as chief instructor at Swords of Chivalry. There, he instructs kids and adults in the finer points of swordplay as well as the history of weapons fighting, answering questions about why maces and morning stars were used in certain battles, and foam pool noodles in others. Students are closely monitored to ensure safety and to foster a respectful attitude toward combat.
