Mat steel color. Shape similar to series 2 but thinner, it is strong in the same way because it is made in steel 110. It is indicated to several styles of fishing but it is suitable in particular, in the small sizes, for research fishing with those delicate baits like ver de vase. Sizes from 9 to n. 0/3 have longer shank, so it is very good for fishing mackerel and to be hooked with big sea worms.
