  • Tetsubishi – are the tiny steel «spikes» that are used when shaking off the pursuer. When chased, the Ninja used to spread the handfuls of these spikes behind. The spikes are made to be thrown on the earth and pierced there with the other spiked edge looking upward. A single spike was enough to stop the enemy since the warriors of that time would wear straw sandals and it was too painful to step on such spikes once.
