What is suntetsu weapon?

Suntetsu is a Japanese weapon that is also known as a "fist iron". It is a small, hand-held weapon that is made of metal and is designed to fit in the palm of the hand. The suntetsu is typically used for self-defense or as an offensive weapon in martial arts.

The suntetsu weapon consists of a thin, rectangular piece of metal that is roughly the size of a credit card. The metal is curved in such a way that it can be held comfortably in the hand. There are usually two projections on the back of the suntetsu that can be used to strike an opponent.

The suntetsu was originally a farming tool that was adapted for self-defense by the Japanese samurai. It was used to strike an opponent's pressure points to incapacitate them or to inflict a painful blow. Today, it is still commonly used in martial arts training and self-defense classes.

Because of its small size and ease of concealment, the suntetsu is also a popular weapon for law enforcement officers and security personnel. However, its use as a weapon has been restricted in some countries due to its potential lethality.
