To Series Katana
To Series Katana
The To Katana takes a material-led approach, carrying the copper treatment across the saya, tsuka, and tsuba rather than reserving it for the fittings alone. Against that continuous metal surface, the patterned blade and small turquoise accents read as deliberate points of colour.
Three size versions are available within the same design, so the series keeps its visual language while changing its overall proportion. The result is a copper-forward katana with a distinct vintage presence rather than a conventional wood-mounted finish.

Materials & Craftsmanship
We choose the right steel for each katana—nothing more, nothing less |
|
One continuous piece of steel, from blade to handle |
|
Through-hardened or clay-tempered, years of experience get it just right |

Hand-Fitted Koshirae
Shaped to follow the katana’s curve, with a secure fit for a smooth draw without slipping loose |
|
For centuries, the tsuba has reflected its owner’s taste—and is often the first detail to catch the eye |
|
A comfortable shape, a tight wrap—the first step to bringing out a katana’s true power is a firm grip |
