“NEW EXTREME” Vibra Wedge spinnerbaits feature a precision ground tapered shaft, ground from .041 to .018, for maximum vibration. This was an improvement from the older version which went from .041 to .028. When you add that modification to amazing high-quality craftsmanship and components, such as our hand tied skirts and patented Wedge blade combinations, you end up with one of the finest high-end quality spinnerbaits on the market.
