The legendary treasure sword CB.Masamune is a center balance long jig developed for slow jigging, focusing on jigging near the coast. As a result of focusing on a slender long body and horizontally oriented high appeal, all lengths were designed with 185mm. In order to produce good water drainage and a variety of actions, the body is made as thin as possible to make the edges work, and the flat surface that is susceptible to water pressure is long and narrow, allowing for tight actions even with short and medium stroke slow jerks. Laser edge back and flat shape.
