The Articulated Micro Shank for Trout Spey flies is a smaller, lighter version of the popular Articulated Shank for Steelhead and Salmon Flies, and is a simple, versatile solution for tying a variety of small, articulated flies such as petite trout wet flies, low-water steelhead flies, sparse streamer designs, and small traditional salmon flies. The wire diameter is small enough to directly attach to hooks as small as size #10.
