The 321 is a multipurpose scud style hook. Use it for general scud and pupa patterns. The shank of this hook is a continuous bend with a down eye. As such, the hook has an offset point and the retention point has been straightened slightly.
This is a standard length hook with a 1X gape. It has a down eye and is formed from a medium weight wire. It is available in sizes #8 to #18.
As with all Firehole Sticks, this hook is made from high strength carbon steel, which is properly hardened and tempered. The hook is chemically sharpened and finished with a black nickel coating.
