A realistic black electric weapon featuring a sharp metal knife blade attached to the end of a long black metal chain. The handle is made of 3D-printed TPU material, matte black, with a built-in momentary pushbutton switch near the grip. Two insulated wires run alongside the chain, connecting to the blade. At the tip of the blade, two metal contact points spark with a visible electric arc, glowing blue-white. The design is sleek, tactical, and practical — with a dark cinematic background highlighting the weapon's shape and sparking effect. Realistic lighting, shadows, and materials. See more
