Kuruma Sukashi Tsuba with Sekigane 車輪透鐔

Tsuba (Sword Guard) “Kuruma”｜Hand-Polished Iron Wheel Motif with Black Patina Finish

The “Kuruma” (車輪) tsuba is a classic iron sukashi-style (openwork) guard characterized by its radiating wheel pattern. Each spoke is precisely hand-cut and polished, forming a harmonious circular geometry that balances strength and lightness. The surface is finished with a traditional black patina (煮黒仕上げ), giving the iron a deep, subdued sheen while preserving the texture of hand-forged steel.

Copper sekigane (責金) inserts reinforce the nakago-ana, reflecting traditional Japanese craftsmanship where form and function merge seamlessly.

Symbolically, the wheel (kuruma) represents motion, life’s cycles, and the continuous path of discipline — qualities that resonate deeply with the spirit of the sword. Whether mounted on a katana or admired as a stand-alone fitting, the “Kuruma” tsuba embodies precision, balance, and timeless simplicity in Japanese metal artistry
