Easy bottoming with free fall and slow action with tension fall. A metal jig with a horizontal fall is suitable for attracting with the fall action that is a standard for fishing, but metal jigs with a horizontal fall have poor bottoming performance. Therefore, in free fall, the center of gravity is designed to be closer to the front in order to speed up the falling speed of the metal jig underwater and improve bottoming performance. In addition, in addition to the forward tilted center of gravity, assist hooks are installed on the front and back, so when lifting and falling after landing on the bottom, the tension fall maintains a horizontal posture, allowing you to produce a slow fall, which is a basic technique for ajing. is possible.
