Made of virtually unbreakable plastic, the Koga can increase the ability of the average person to defend himself several times over. Designed by martial arts specialist Bob Koga, this straight baton is lighter and more versatile option to the regular side handle baton.
With proper training, it can function as a fantastic aid in leverage when obtaining joint locks or submission holds. Blows struck with the fist may be too weak, or worse, result in a broken hand, while blows struck with a baton may be too powerful resulting in grave injury or even death. The SD however, solves this problem, neatly bridging the gap by concentrating and magnifying the effect of hand blows while minimizing the likelihood of permanent injury or death.
