Hook shapes and names are as varied as fish themselves. In some cases, hooks are identified by a traditional or historic name, e.g. Aberdeen, Limerick or O'Shaughnessy. In other cases, hooks are merely identified by their general purpose or have included in their name, one or more of their physical characteristics. Some manufacturers just give their hooks model numbers and describe their general purpose and characteristics. For example:
* ''Eagle Claw'': 139 is a Snelled Baitholder, Offset, Down Eye, Two Slices, Medium Wire
* ''Lazer Sharp'': L2004EL is a [[Circle hook|Circle]] Sea, Wide Gap, Non-Offset, Ringed Eye, Light Wire
* ''Mustad Model'': 92155 is a Beak Baitholder hook
* ''Mustad Model'': 91715D is an O'Shaughnessy Jig Hook, 90-degree angle
* ''TMC Model 300'': Streamer D/E, 6XL, Heavy wire, Forged, Bronze
* ''TMC Model 200R'': Nymph & Dry Fly Straight eye, 3XL, Standard wire, Semi-dropped point, Forged, Bronze

The shape of the hook shank can vary widely from merely straight to all sorts of curves, kinks, bends and offsets. These different shapes contribute in some cases to better hook penetration, fly imitations or bait holding ability. Many hooks intended to hold dead or artificial baits have sliced shanks which create barbs for better baiting holding ability. [[Jig (fishing)|Jig]] hooks are designed to have lead weight molded onto the hook shank. Hook descriptions may also include shank length as standard, extra-long, 2XL, short, etc. and wire size such as fine wire, extra heavy, 2X heavy, etc.

==== Single, double and triple hooks ====
Hooks are designed as either ''single'' hooks—a single eye, shank and point; ''double'' hooks—a single eye merged with two shanks and points; or ''triple''—a single eye merged with three shanks and three evenly spaced points. Double hooks are formed from a single piece of wire and may or may not have their shanks brazed together for strength. Treble hooks are formed by adding a single eyeless hook to a double hook and brazing all three shanks together. Double hooks are used on some artificial lures and are a traditional fly hook for Atlantic Salmon flies, but are otherwise fairly uncommon. Treble hooks are used on all sorts of artificial lures as well as for a wide variety of bait applications.
