I personally use this hook extensively for stonefly patterns and caddis emergers. In the smaller sizes it makes for a good klinkhammer hook. Many tyers have used it for Czech nymphs and carp flies as well.
This is a standard length hook with a 2X gape. It has a straight eye and is formed from a heavy weight wire. It will initially be available in sizes #8 to #18 with the potential of sizes #6, #20, and #22 in the future.
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.
