C&F Design’s 3-in-1 Clipper/ Threader - From Tom Lewin Frontier Flyfishing

Threading tippet through the eyes of tiny flies can be a real mission, especially in the half light of dawn and dusk. This handy little tool combines a razor sharp clipper with a threader that makes tying on even the tiniest of flies super easy. Simply flip out the threader, push it through the hook eye and use it to pull the tippet through. Brilliant!
