Spirit River's machining is unparalleled and their plating is exceptional. As leaders in quality, Spirit River takes pride in all their nickel products, including these cones. Each cone is individually machined using a screw machine, and then tumbled to remove any visible machining marks. The cones are then plated with a high-quality finish, ensuring a longer and slightly more expensive process, but a superior end result. For those who value their time spent tying flies, these cones are perfect when extra weight is needed for streamers, sculpins, and deep running minnow patterns, surpassing the capabilities of Brite Beads. Trust Spirit River for top-notch cone heads.
