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.
