All OPST Swing Hooks come barbless, causing the minimum possible amount of damage and stress to fish and people alike. The slightly upturned eye produces an optimal line of pull into the fish, and enables proper fly assembly when using shanks, tubes and string leeches. The round bend produces superior hook strength and holding ability. OPST Swing Hook points are offset, exposing a larger purchase area to fish, resulting in more hookups and fewer lost fish. With their upturned points, our short-shanked hooks resemble circle hooks, and as such they tend to produce more hookups in the corner of the mouth than a normal straight-shanked J hook. All in all, OPST Swing Hooks are highly specialized, fly fishing specific, fish friendly hooks that will penetrate instantly and hold longer.
