Thin arms are deformed and do not provide good hooking. Thick arms have difficulty transmitting the vibration of the blades to the body. The spinnerbait SWAGY solves such dilemmas. The lower arm with a diameter of 0.95mm is tough enough to resist deformation. The upper arm with a diameter of 0.6mm transmits the vibration of the blade to the entire body, causing the skirt to act in a glossy manner. The head is made of tin and tungsten. By concentrating the high specific gravity tungsten on the bottom surface, it stabilizes swimming even at fast reeling speeds, and reduces trouble with hooks getting caught by quickly rising up after avoiding obstacles.
