The flat body and half ribs allow the worm to bend in one direction the moment it bites. This prevents the worm from curling up and makes it easier for the hook to come out, improving hooking performance. The key to the bite is the slight vibrations emitted by the fine ribs carved into the body. The moment it hits the bottom, it automatically appeals to the angler and brings it into the bite without the angler knowing. The body and tail are designed with an exquisite balance, and the worm can be used without rotating even when falling with a heavy sinker or during high-speed retrieval.
