Easy bottoming out with free fall, slow action to invite with tension fall. Horizontal fall metal jigs are suitable for invitations in fall action, which is the standard for aging, but horizontal fall metal jigs have poor bottoming performance. Therefore, in the free fall, the center of gravity is designed to be closer to the front for the purpose of increasing the fall speed of the metal jig underwater and improving the bottoming performance. Also, since the assist hook is attached to the front and back in addition to the center of gravity tilted forward, it is possible to produce a slow fall, which is the basic technique of ajing, by keeping the horizontal posture with a tension fall at the time of lift & fall after landing.
