Square building crank "Macbeth" corresponding to full-scale cover cranking. In order to quickly recover the posture after avoiding obstacles, which is an essential condition for the cover crank, the low center of gravity fixed weight with integrated front hook eye and the thin side part make it easier to catch water. Adopted a slash edge lip. The front hook does not easily interfere with the body, and noise during retrieval has also been reduced. We also verified the synergistic effect of paint and the body shape on the back to effectively create blinking during action. It is a self-confident work that is packed with attention to detail in a seemingly ordinary crankbait.
