The Wedge Blade is one of the most popular blade design for spinnerbaits ever made. What makes it special is the special variable thickness of the blade. The front of the blade has a thickness of .015 and increases in diameter to .030 to the back of the blade. This is a special two-part manufacturing process to achieve the final product. The result is an increase in vibration that causes the bait to rise in the water column. They are available in nickel and gold plated colors and two sizes #4 and #4.5. They also come in a two or a three-pack. The #4 blade is typically used for 3/8oz. spinnerbaits and #4.5 used for 1/2oz. and 3/4oz. spinnerbaits.
