The head has a hybrid shape of a bullet type and an arrowhead type that creates a stable horizontal posture when "just winding" and supports "dirt action". The glider fins on the side of the head improve range retention and contribute to a longer dirt width as if gliding in dirt. It uses a hook with good piercing and high toughness, and tenaciously responds to fights with large sea bass. The wire keeper maintains high holdability while enabling beautiful worm settings.
