The body shape and balance are "symmetrical" and "center balanced". Compared to asymmetrical bodies, the action is more likely to be irregular, and the momentary irregular action that occurs during a certain action acts as a trigger to turn on the fish's predation switch. In addition, by giving the body thickness despite being made of lead, it is possible to achieve a high weight despite its small and compact body shape. It maximizes the advantages of lead jigs, which can fall and act slower than tungsten jigs, and appeals the jig's presence in the water for a longer period of time to the target. It has significantly increased the chance of a bite. In addition, the jig rotates like a tornado when jerking or falling. This tornado spin, which creates a flashing effect, a disillusionment effect, and a water stirring effect, exerts an outstanding appeal to fish far away. It is compact yet highly appealing, and with its action and fall that create many bite opportunities, it has been tested repeatedly over a long period of time in various fish species and situations such as blue fish, rock fish, and cutlassfish, and has been finished as a truly all-rounder jig that has been consistently over-excited.
