Metallic threads are used primarily for decorative applications, and are generally not strong enough to be used for wrapping rod guides. Metallic threads are highly reflective, do not need a color preserver applied before the finish, come in a wide variety of colors, and are an ideal choice for decorative trim wraps around handles, winding checks, hook keepers, and rod guides. Alps, DMC, Madeira, Prizm, FishHawk and Birch all have a range of metallic rod building threads.
