Not the standard of metal jigs, but the "standard of rocky shore metal jigs". The base action is a sharp long slide and a fluttering horizontal fall that is effective for various targets. It is exactly the finish suitable for Rocky Shore's default equipment. By putting the line eye in the open mouth and bringing the point of effort closer to the center of gravity, it demonstrates a high action response. High-dimensional representation of the jerk action intended by anglers. The horizontal and slow fall with roll that occurs in the free fall creates a floating feeling as if it stopped for a moment due to the sharp slide and the sharpness difference. It secures the pauses for bites.
