Anatomy of a Hook
By Steven H. McGarthwaite (aka: Parnelli)


When we tie a fly, we start off selecting a hook on to which we tie material to create the fly pattern. This is no different when building a car, you have a car frame onto which will go all the components of the car, and the body which will cover the assembly.

As you tie flies on your vice, have you ever given thought to the anatomy of the hook that you are using? Your recipe for the fly pattern may call for a Hook Model Number, by a Specific Manufacturer. It may give you the range of hook sizes the fly can be tied with. But have you given further thought to the components, that make up the hooks shape and design?

This information is helpful when selecting the size thread you will use, the amount of materials you will apply to the fly, and the placement of the material. In short, how are you going to get all the stuff on the hook and have an end result that looks like the fly pattern you are tying!

First thing we have to do is have a basic terminology. The basic hook is made up of 7 components:

    1. Eye
    2. Shank Length
    3. Bend
    4. Throat
    5. Gap Width
    6. Barb
    7. Point

Hooks are sold by Manufacturer Brand Name, Hook Model Number, and Size of Hooks Gap. As the size of the Hook Gap decreases, the Shank Length also decreases. This means that you will need to use a smaller size thread, use less material, and adjust size of the different parts of the fly's construction.

Here is an example of how the Standard Dry Fly (Mustad 80010BR) Shank Length changes as the size of the Hook Gap decreases. As you can see everything is not proportional, as the size decreases.


Please check out the Fly Tying Section, on the Bulletin Board, on FAOL too.

If you have any questions, tips, or techniques; send them along. Someone else thought up most of this material before we did, they just forgot to tell anyone about it. Or else we just forgot about it, while learning something else. Let us share with each other, all the things we know! ~ Steven H. McGarthwaite (Chat Room AKA Parnelli)
