Made from high strength, corrosion resistant Type 304 stainless steel, 49 Strand 7x7 cable provides excellent kink resistance and bit protection against shark and other big game toothy fish. This motion can kink single strand leader wire and can actually be more destructive to your tackle than the fierce bite. 49-Strand resists kinking, wrestles back, and allows you to hook up and haul in. This leader is designed for the hard hitting big game species like tuna, sharks or barracuda in salt water conditions. If you have ever had your line cut with a light duty leader by ferocious teeth of sharks, tuna or barracuda, you know how important it is to have a quality leader that can take abuse and not break down. Made in the USA by AFW.
