This revolutionary bokken design is the closest you can get to sparring with a real katana! Designed for the sword training martial artist who requires full force practice, this patent pending design is a vast improvement over traditional bokken and kendo shinai. Measuring 46" overall, this item features a tension curved bamboo blade that allows training moves that cannot be done with a normal bokken such as a rolling thrust parry. The unique flexible spring blade reduces the bruising effect on unprotected parts of the body by absorbing more of a full force blow than a standard bokken. Excellent item for the martial arts enthusiast! United Cutlery, UC1494.
