MUSTAD hooks are made from premium hi-carbon steel, which gives the hooks maximum strength.  MUSTAD’s unique tempering process ensures even strength and high quality. Before being tempered the hooks are forged, which in this context means that the hook wire is a bit compressed. By doing this, the strength of the hook is increased by over 30%!

34011   Classic Fly Hooks NOW: S74SZ-34011

Saltwater fly hook, Z-Steel. The 34011 (no longer available) style hooks from Mustad have been replaced with the S74SZ-34011. Please note that these replacements are the same great hook, just like the 34007 but with a shank that is 3/8" longer and now Z-Steel. This makes the S74SZ-34011 an ideal hook for longer patterns such as worms and sand eels. 

The Mustad S74SZ-34011 features Mustad's unique Z-Steel alloy which is applied over high carbon steel for a hook that greatly surpasses stainless steel in both strength and corrosion resistance. Z-Steel combines extreme corrosion resistance with hi-carbon steel, resulting in hooks that are sharper, stronger and virtually indestructible in even the most demanding fishing conditions.

The S74SZ-34011 streamer hook additional features: - Straight shank - O'Shaughnessy bend - 2 extra heavy wire - 4 extra long shank   Mustad Signature fly tying hooks are designed with consistent hook gap, bend, wire diameter and shank length for precise scaling and feature a chemically sharpened needle point with microbarb.
