Kubatons are very effective weapons that can be used in a number of ways such as swinging the keys at an attackers face, punching the tip into sensitive areas of the body, or using as a bar to leverage the wrist of an attacker that is grabbing you.
Kubatons are an EXTREMELY effective method of "leveling the playing field" when attacked by a larger or stronger opponent. They are extremely easy to use and are a non-lethal means of defending yourself. These kubatons have a textured matte finish that will look better much longer. Also, the key ring end has a slight dish shape to better contour to your thumb.
Light weight, extremely high strength polymer. Much lighter than aluminum kubatons.
