One of the elements that makes flat-bodied soft bait effective is "strong water pushing" and the accompanying "spontaneous irregular slide action". The Hira Tailor is designed with a block-shaped bellows body with deep slits to add complexity and luster due to turbulent water flows. The strength of the water pressure on the body gives it a luster that wriggles in all directions.
In addition, the deep slit firmly grips the water throughout the body, so it always emits complex vibrations and appeals its presence even when staying. Even for delicate rod work, which is difficult to produce with conventional flatworms, it attracts fish with its soft and twisting reaction.
The flexible body due to the slits also contributes greatly to the improvement of poor hooking, which is a drawback of flatworms.
