Katana with groove (Bo-hi) – Lightweight and balanced replicas for Iaido
In this category you will find katana replicas with a groove (bo-hi), which are sought after for their lightness and excellent handling. Bo-hi is a longitudinal groove on the blade, whose primary purpose is to reduce the overall weight of the weapon while maintaining its structural strength. This modification changes the balance point of the katana, making it an ideal choice for those who prefer speed and precision of movement.

Function of the Bo-hi groove and its benefits for training
The lighter blade increases handling speed and makes it possible to perform technical forms with less physical effort. This is especially important during long-term study of traditional arts, where emphasis is placed on correct form and fluidity. A unique feature of these katana is the acoustic effect known as “Tachi-Kaze” – the sound of the sword wind. When the swing is performed correctly, the groove cuts through the air and produces a characteristic whistling sound. This serves as immediate feedback confirming the correct blade angle (Hasuji) during training.
Why choose a katana with groove?
- Excellent balance: The lighter blade shifts the balance point closer to the guard (Tsuba), which makes tip control easier and allows lightning-fast changes of direction.
- Acoustic control: The Tachi-Kaze effect is an invaluable aid in Iaido practice, because you can hear every mistake in your swing technique.
- Reduced fatigue: The lower weight helps save your joints and muscles during repeated fast movements.
- Elegant design: Bo-hi gives the katana a dynamic and visually refined appearance that is highly appreciated by collectors of Japanese replicas.
