By sting
The stinger is the sharp part of the hook. Its purpose is to pierce the fish's lip. The better its sharpening, the higher the quality of the cut.
Knife edge
This type of stinger is designed to cut cartilage and fish bone. Well suited for fishing with "hard” by mouth Disadvantage - it can create a large incision in the mouth, after which the fish emerges.
Needle
Sting type "Needle" does not penetrate the fish as effectively as a "knife blade", but its advantage is the absence of a tissue cut, which means that the chance for the fish to hatch is significantly reduced.
Short Sting
In a short sting, the barb of the hook is much closer than on ordinary hooks.
Beak
The beak of the stinger has a characteristic bend towards the tip.
Spear
A spear is the most common type of stinger. More universal purpose. The hook penetrates reliably and causes minor damage to the fish's mouth. The sting of such a hook can be bent to the left or to the right.
Rolled in
This type of hook has a point that is directed towards the eye of the hook. Better holds fish that actively resist.
Kirbed and Reversed
In these variants, the stinger is deflected to the side in relation to the shank. Those hooks whose barb is deflected to the right (when viewed from the side of the barb) are called kirbed, and reversed are those in which it is deflected to the left. The advantages of this type of stinger are better cutting. Reversible hooks are more popular due to the fact that most fishermen are right-handed and it is more convenient for them to bait these hooks.
