The "Hammer K"

Justin King

This is probably Justin's most effective pattern that he's tied to date. The action you get by trimming the crustaceus brush tight is unreal! Take your time tying this streamer. Effectively trimming the crustaceus brush and Senyo's head is the key to making it proportionally correct. I've been fishing this fly for the past year and it never lets me down!
