We reinforce concrete and steel for construction and plastic for insulation. Sometimes, it just might be necessary to reinforce your fists. In 1947, Professor Frank A. Matsuyama developed an eight-inch plastic stick he called a yawara stick, named for an early Japanese martial art.
It became a popular item for Japanese police – many of whom were ex-servicemen with some basic knowledge of hand-to-hand combat and some who were experts in jujitsu, judo or boxing – as it was easier to use than a nightstick and easily concealed. Held in a fist, it can significantly reinforce a punch and do considerable damage, especially when that punch lands on a bony area of a person’s body. I definitely like the idea of something small, basic and portable that could make the difference in defending myself from an attacker!
Check out this pamphlet on the yawara stick, a very basic close combat weapon that increases combat effectiveness.
As with any weapon, a yawara stick should be used only when absolutely necessary in a self-defense situation. If it is illegal to carry a yawara stick where you live, there are many alternatives. A titanium stick, hair brush or even a magic marker held in a fist would serve as a reinforcement to a punch.
If you have ever used such a weapon while in self-defense mode, let us know if it worked for you. What other items have you held in your fist to reinforce a punch?
