Fishhooks come in myriad sizes, shapes and styles. Even individual features vary for the same hook. Let’s take a look at hook eyes.
Upturned eyes are bent away from the point. Best for use when snelling hooks; knots tied directly rotate the point away from the fish’s mouth.
Straight eyes are in line with the point. Best for use when using a knot tied directly to the eye of the hook; the point remains in line
on the strike.
Down-turned eyes are bent toward the point. Best for use when snelling hooks to line or leader; knots tied directly rotate the point toward the fish’s mouth.
Ringed, welded, parallel and even eyeless hooks also exist. Consider these things when you buy hooks.
