The Tsumetogi is a sleek, high-tech katana with a blade that emits a faint blue glow, indicating its cryogenic enhancement. The handle is wrapped in black carbon fiber for grip, with silver accents that contrast sharply against the dark material. The blade itself is made of a futuristic alloy, appearing almost translucent with a frosty sheen, and features intricate circuit-like engravings that pulse with energy when activated.
