Shimano's Swagy spinnerbait incorporates an innovative tapered-wire design to add durability without sacrificing the lure's vibration. The lower arm's thicker (0.95mm) wire improves hookup ratios and adds durability. Swagy's upper arm tapers to a thinner (0.6mm) wire, boosting the lure's specially-designed blades to transmit more vibration through the lure body and causing the skirt to have more action as the lure moves through the water. The shape of the blade's front cup creates a faster rise, enabling the lure to run with extreme vibration to draw aggressive strikes.
