Peux Revo Pro Nipper and Threader

The Peux Revo Pro is the best designed nipper multi tool we've seen yet to facilitate the easy threading of hook eyes with fine tippet. To use the threader tool, slide the black clamp downward, pick the slot size that fits the eye of your fly, and let the black clamp slide back in place. The hook is held in place by a magnet in addition to the clamp. Then thread the tippet from one side or the other through the fly. Pull the clamp down to release the fly and tie your knot to the fly.
