HOOKS
Hooks used for fly-tying differ somewhat from those used for bait fishing etc., inasmuch as they are usually hollow ground, and tapered shank especially those used for dry flies. The tapered shank next to the eye allows the head of the fly to be tied smaller, and also reduces the weight of the hook, an advantage for dry flies. Of course flies may be tied on any style or grade of hook, but considering the work involved in making the fly, and realizing that with an old razor blade the fly can be quickly removed from the hook should the first attempts prove unsatisfactory, you will see the advantage in using good hooks.
