Legendary professional bass angler, Kevin VanDam, spent a considerable amount of time designing and fine-tuning the original HC Square Bill. The all-new Strike King KVD 1.5 Hard Knock utilizes the same proven size and shape as the original, but now with a hawg-calling Hard Knock rattle system. Delivering exceptional erratic action with wandering and searching motions, they are perfect for enticing bass holding shallow.
