Koppo stick - self-defence

thingiverse

Middle Kubotan brother. Applied as a self-defense tool, some of its usage can be similar to that of the yawara stick or Kubotem. The principal targets in self-defence include bony, fleshy and sensitive areas such as knuckles, forearms, the bridge of the nose, shins, stomach, solar plexus, spine, temple, ribs, groin, neck and eyes. Hold the Kubotan in either an icepick grip (for hammerfist strikes) or forward grip (for stabbing, pressure point attacks and seizing). Common uses include hardening the fist (fistload) for punching, attacking vulnerable parts of an assailant's body, and gaining leverage on an assailant's wrist, fingers and joints. With keys attached, it can function as a flailing weapon. As a pressure point tool, it can attack any spot a finger can, but with greater penetration due to the smaller surface area at the ends. After assembly, pass the cable through the middle holes. Before use, slip two or three middle fingers through the loop; this will secure the Kubotan stick from falling out.
