Anzóis têm sido empregadas há séculos pelo homem, como ferramenta para obtenção de proteína de excelente qualidade, normalmente ligado a uma linha resistente e a outros aparelhos que permitam retirar o peixe da água.

==Hook types==

There are a large number of different types of fish hooks. At the macro level, there are bait hooks, fly hooks and lure hooks. Within these broad categories there are wide varieties of hook types designed for different applications. Hook types differ in shape, materials, points and barbs, and eye type and ultimately in their intended application. When individual hook types are designed the specific characteristics of each of these hook components are optimized relative to the hook's intended purpose. For example, a delicate dry fly hook is made of thin wire with a tapered eye because weight is the overriding factor. Whereas Carlisle or Aberdeen light wire bait hooks make use of thin wire to reduce injury to live bait but the eyes are not tapered because weight is not an issue. Many factors contribute to hook design, including corrosion resistance, weight, strength, hooking efficiency, and whether the hook is being used for specific types of bait, on different types of lures or for different styles of flies. For each hook type, there are ranges of acceptable sizes. For all types of hooks, sizes range from 32 (the smallest) to 20/0 (the largest).

 

===Points and barbs===

The hook point is probably the most important part of the hook. It is the point that must penetrate fish flesh and secure the fish. The profile of the hook point and its length influence how well the point penetrates. The barb influences how far the point penetrates, how much pressure is required to penetrate and ultimately the holding power of the hook. Hook points are mechanically (ground) or chemically sharpened. Some hooks are barbless. Historically, many ancient fish hooks were barbless, but today a barbless hook is used to make hook removal and fish release less stressful on the fish. Hook points are also described relative to their offset from the hook shank. A kirbed hook point is offset to the left, a straight point has no offset and a reversed point is offset to the right.

Care needs to be taken when handling hooks as they can 'hook' the user. If a hook goes in deep enough below the barb, pulling the hook out will tear the flesh. There are three methods to remove a hook. The first is by cutting the flesh to remove it. The second is to cut the eye of the hook off and then push the remainder of the hook through the flesh and the third is to place pressure on the shank towards the flesh which pulls the barb into the now oval hole then push the hook out the way it came in.''

 

===Eyes===

The eye of a hook, although some hooks are technically eyeless, is the point where the hook is connected to the line. Hook eye design is usually optimized for either strength, weight and/or presentation. There are different types of eyes to the hooks. Typical eye types include the ring or ball eye, a brazed eye-the eye is fully closed, a tapered eye to reduce weight, a looped eye—traditional on Atlantic Salmon flies, needle eyes, and spade end—no eye at all, but a flattened area to allow secure [[snell knot|snelling]] of the leader to the hook. Hook eyes can also be positioned one of three ways on the shank—up turned, down turned or straight.
