The size 7 FB (cascade or mag willow) blade measures 2 1/2" W x 1 1/2" wide. It has a fold down the middle and has long been a mainstay in the arsenal for Salmon fisherman who build trolling style spinners. It has also become popular in recent years for big spinners used for Musky or Pike. As with all our blade selections, availability is fluid with many new patterns making their way into inventory pretty much all the time.
