Premium same tool body as Starter tool. The big difference are the two premium, machined, tapered, and hardened mandrels. An elegant and effective solution for holding tubes. Made of steel in the USA. Clamp the tool in any vise that accepts a 2/0 hook, and you can tie tube flies with ease. Comes with two mandrels, sample plastic, aluminum, and copper tubes, junction tubing, sample tube fly hooks. Instructions included. Still a great package at a great price.
