The TKI-20 Shingen is a high-tech, futuristic katana with a sleek, angular design, featuring a monofilament edge that glows faintly with a neon blue hue. The blade is constructed from advanced carbon-fiber composites, giving it a lightweight yet incredibly durable structure, while the hilt is wrapped in synthetic leather for a secure grip, accented with cybernetic patterns. The guard is minimalistic, with sharp, geometric lines and embedded circuitry that pulses with energy when activated.
