Black and White Katana Sword

A Hamon Unlike Any Other

The gunome-notare hamon running the full length of this blade is among the most visually arresting temper line patterns a production katana can carry. Large, rhythmic waves rise and fall in a continuous undulation from the hamachi all the way to the kissaki, where the boshi curves cleanly around the tip and returns along the spine. At its widest points, this bright, high-contrast habuchi line occupies nearly a full third of the blade’s width, turning the entire ji into a display of light and shadow. The T10 steel surface, polished to a cool silver clarity, amplifies every arc of the pattern, creating the kind of visual depth that rewards long, close attention. This is a black and white sword built around a blade that earns its place at the center of any collection.

The Art of the Fitting

Every fitting on this katana was chosen to reinforce the same high-contrast visual language. The tsuba is a statement in itself: a stylized organic silhouette in deep navy blue enamel with scattered floral motifs in raised gold-tone relief and a defining brass border, unlike any conventional guard form and impossible to overlook. The handle is wrapped in a tight, even hineri-maki diamond pattern in crisp white synthetic leather over a black-dyed samegawa base. The fuchi and kashira answer each other in blackened metal engraved with gold curvilinear motifs evoking Edo-period decorative metalwork. Gold-tone menuki anchor the grip at their traditional positions. The saya is covered in glossy black granulated leather, its textured surface echoed by the matching black and gold metal fittings at its tip and mouth. White, black, navy, and gold every element holds its place in a composition that transforms this katana into a centerpiece worthy of the finest display spaces.
