The rotation resistance of the small blade on the jaw keeps the target range long while maintaining a forward leaning posture. Due to the vibration of the body, the rotating blade sways irregularly, achieving a higher flushing effect. With a high-speed retrieve with a moderate pitch, the resistance to swim is lost to the rotation resistance of the blade, creating a moment when the lure slips out. This "pause" that comes out becomes an "eating kick" and makes the bus use its mouth. The rattle sound that produces high frequencies and calls the bass increases its appeal. Bring out the sickness of the bus. We succeeded in creating "timing of feeding" by attaching a blade to the vibration plug, which had a poor performance of timing to eat in a swim without change. This is "the power of the chin"
