Product Description

This might be the smallest possible katana—any shorter and it would fall into the wakizashi category.
Compared to standard katanas, this model is noticeably more compact, lighter, and faster.
In fact, it is one of the best-handling blades we have ever produced.

Weighing only 660 grams, it feels extremely light and agile in the hand. The tuned balance gives it exceptional responsiveness, making cuts and movements incredibly quick. During use, it produces a clear, strong tachikaze (whistling sound), making it ideal for form practice and precision training.

Despite the ultra-lightweight build, durability is not compromised at all.
Constructed from S7 tool steel—famous for extreme impact toughness—the blade maintains structural integrity far beyond what its weight suggests. The mirror finish, true yokote, real bo-hi, and gilded paper-crane fittings complete a beautifully crafted and high-performance weapon.

This is a rare combination of extreme lightness + elite toughness, made possible only by S7 steel.
For practitioners seeking maximum agility and control, this katana is unmatched.
