Variants of the Shinai
There are different variants of the bamboo sword. Fukuro Shinai is the name of the original model. In this one, only a bamboo cane was divided into two at the tip. However, a small leather hood served as protection against injuries.

Thus, they better control the movements. Furthermore, the appearance of this sword is convincing. It looks very similar to the weapon of the samurai.

- There are different approaches to test the attacker. Fureru stands for gently touching the opponent’s sword. In this way, fighters find out whether their partner is in doubt or has made a firm decision. This exercise definitely requires a partner.
- Osaeru is the technique in which fighters aim to cover their opponent’s sword with their own. They usually try this at the moment when the attacker is about to strike.
- With the Hajiku thrust, Kendoka block the strike approach of their attacker. Uchiotoshi refers to knocking down the opponent’s sword
- Harai stands for the diagonal lunge. Thus, fighters shake the center of their opponent. They then immediately go on the counterattack
- Makiotoshi stands for turning out the opponent’s sword. Kendoka use this technique when their opponent has a strong grip.
