The body of the lure, which incorporates a fin keel, has been reconstructed from scratch to balance the flight and swimming performance required of a sinking pencil, including the bend curve, the ratio of body height to width, the cut of the face, the weight distribution, and the position of the eye, all while simplifying all the elements. When reeling, the tail swings widely from side to side, and the water hitting the face, including the fin keel, causes the head to drift from side to side, creating a "swing slalom action." The Levin (Light) has a lighter weight, which further enhances the water-gripping power of the fin keel. The slide width becomes wider when it falls in the water, and it is characterized by its ability to swing its tail lightly while drawing the largest S-shape of the Levin series. It can handle a wide range of retrieve speeds and changes in flow rate, and it is possible to maintain the shallow range of approximately 40cm below the surface of the water with the Levin's unique tenacious swimming, even in strong currents or when reeling quickly.
