The hand, inherited from the Ebi Shad, trembles when falling or dragging, generating a slight vibration that catches fish.
The horizontally attached square tail emphasizes the water push when it falls after catching water.
Even during action, the unintentional irregular movement inherited from the Ebi Shad, which sometimes moves and sometimes doesn't, is an element that catches fish.
Not only is the standard water-pushing body, which is important for high-density no-sinkers, but the unique tail also adds water push that pushes through.
