Fish hook : Anatomy and construction

    Commonly referred to parts of a fish hook are: its point - the sharp end that penetrates the fish's mouth or flesh; the barb - the projection extending backwards from the point, that secures the fish from unhooking; the eye - the end of the hook that is connected to the fishing line or lure; the bend and shank - that portion of the hook that connects the point and the eye; and the gap - the distance between the shank and the point. In many cases, hooks are described by using these various parts of the hook. Example: Wide gap, 2X Long Shank, Hollow Point, Turned Down Ring Eye Bait hook. Contemporary hooks are manufactured from either high-carbon steel, steel alloyed with Vanadium, or stainless steel, depending on application. Most quality fish hooks are covered with some form of corrosion-resistant surface coating. 


    Corrosion resistance is required not only when hooks are used, especially in saltwater, but while they are stored. Additionally, coatings are applied to color and/or provide aesthetic value to the hook. At a minimum, hooks designed for freshwater use are coated with a clear lacquer, but hooks are also coated with gold, nickel, Teflon, tin and different colors. Mustad, for example, produces hooks in six colors, including black.
