Koga

Koga Defense Tool, top picture Mini Koga inset

Made of virtually unbreakable plastic, the Koga SD1 can increase the ability of the average person to defend himself several times over. With proper training, it can function as a fantastic aid in leverage when obtaining joint locks or submission holds and to target pressure points. But where it really shines is as an intermediate impact tool. The Koga works by concentrating and magnifying the effect of hand blows while minimizing the likelihood of permanent injury or death. Using it is better than a bare fist, but less than a baton.
