Any threader is designed to make putting thread into a bobbin, or fly line into the eye of the fly easier. The aluminum, stainless steel spring wire, and epoxy we use make our “thread” superior to the rest: finger friendly shape, wire that can be bent and pinched without breaking, and two wires so that when you somehow break one you have another.
