Jerry Hossom is one of the top U.S. custom knife makers and a true artistic national treasure. He very kindly gave Jeff Modell and Modell Design LLC permission to make Butterfly Swords based on his famous Retribution knife. As Jeff explains it: "Jerry Hossom's design was already perfectly suited for BJD so all we did was scale them for Wing Chun making only those adjustments deemed necessary to accommodate a D-Guard. Because of the weight of the D-Guard we cannot make the blades as extraordinarily thin as his knives, nor do we imagine the quality of these swords is on par with his personal work but these are still superb. They are fast and sturdy.
