Compared with ordinary braided wire, the clad steel wire has higher strength, lower expansion and better sensitivity. We use high-quality raw silk to weave, and add steel wire to the core during the weaving process, which greatly increases the firmness of the fishing line, enhances the plasticity of the fishing line, and is not easy to wind or roll. The surface is smooth, the tensile force is strong, the abrasion resistance is strong, and it can quickly enter the water.
