The Partridge K12ST is designed for both Sedge and Caddis patterns. Featuring a standard wire, long shank and a forged "sweeping" bend for added strength. This pattern was the original pattern for paving the way for the development of the K14 and 15BN patterns, copied by many over the years. Its also great for most emerger patterns. Finished in black nickel, with a straight-eye and bronze finish.
