The Picasso Shock Blade Pro is manufactured to bring you the very best in innovation and technology. The Patented design creates a lot of thumping vibration and hunting action even when reeled at a very slow retrieve. That creates a hard thumping vibration with a wider wobble, While the standard blade creates a very tight/quick action and vibration that can be "Burned" or "Ripped". Our design helps to keep the lure down and in the strike zone longer without rising which is a common complaint of other bladed swim jigs on the market. Staying in the strike zone means more fish in your live well.
