Hareline Brass Eyes. Brass barbell fly tying eyes. Hareline recognizes that some fly tyers choose not to use lead wire or lead fly tying dumbbell eyes. This innovative thinking produced an extremely high quality series of fly tying eyes, dumbbells, or barbells whatever name one chooses to use that serve the same function of the traditional lead fly tying barbell eyes without the lead. Quite amazing, we think. Hareline brass fly tying barbell eyes are high on our Caddis Fly Pro staff list of favorites. They are stout, smooth, shiny, available in sizes from X-small to large, and they get the job done. Hareline brass fly tying barbell eyes offer an additional advantage over lead barbells also.

Simply stated, flies tied with Hareline brass fly tying barbell eyes look hot, fish cool, and catch fish by the boat-load (when the fishing is really, really, really good).
