The Shinai is a practice weapon used in the Japanese martial art of Kendo. It consists of a simulated sword made of bamboo, designed to simulate the shape and weight of a traditional katana. The Shinai allows practitioners to train safely by reducing the risk of serious injury during simulated combat. Its flexible and resistant design helps absorb the impact of blows, allowing students to focus on technique and control. It is an essential tool in training skills and preserving the traditions of Kendo.
