The Yaiba Kusanagi CT-3X is a high-tech, futuristic katana with a sleek, elongated blade made from a composite of carbon fiber and nano-enhanced steel, giving it a dark, matte finish with subtle neon blue circuit-like patterns that glow along its length. The handle is wrapped in black synthetic leather with grip-enhancing texture, featuring a minimalist, angular guard that emits a faint blue light. The blade's edge is razor-sharp, with a slightly curved, asymmetrical design that emphasizes its cutting power and speed. The overall aesthetic combines traditional Japanese sword elements with cutting-edge cyberpunk technology.
