The Hitotsu Tenya FD consists of a multi-layer plan, with a hydrodynamic shape that allows it to sink quickly. Small hooks have become very popular with the Japanese and because of their incredible piercing ability they grab the fish from everywhere. Their special feature is that the shot is not tied to the thread, but moves freely along it (Free Slide). The head sinks first, followed by the tentacles and the bait, a movement which is considered completely natural. The Tenya plan is of an indefinite shape and has many sides and angles as a result of which it projects its volume from every possible angle. They are ideal for shallow areas. They have a low center of gravity and due to their shape and movement they stay on the bottom for a longer time.
