Product Description

Although this is a large-size katana, the blade weight and balance point were specially tuned to ensure excellent handling.
In real use, it may actually handle better than many standard katanas without a groove.
The feel in hand is outstanding—responsive, balanced, and powerful.
Cuts are clean, forceful, and full of momentum.
For practitioners who want both visual presence and serious cutting performance, this S7 steel katana delivers on every level.
