The design is similar to Trout Twig, but the action is completely different. The two front sections are connected by a metal shaft,
By setting a screw with the mounting hole offset from the center line on the shaft, the vibrations caused by the unbalanced rotation are transmitted to the two rear sections connected by a thread, causing the tail to vibrate finely.
The thin resin screw rotates firmly even in dead slow motion and appeals to trout with visual perception, water movement, and slight vibration of the tail.
