Made with a dual arm .030 stainless wire making the shaft equivalent to .060. Stronger than any spinnerbait available on the market today! Two separate wires gives each blade its own ball bearing swivel allowing for the max. vibration from each blade and giving the Phase II an entirely different look by each blade spinning on its own swivel. By taking the first blade off the main wire where it would run around that wire on a clevis takes the roll away - making it run truer!
