An increasingly popular hook in the fly tying world not just for trout but pike, musky and other predatory fish also. The smaller size #1 to #4 hooks are ideal for large articulated streamers and other bulky streamers for trout and salmon. The larger 1/0 to 6/0 sizes have become the industry standard for pike, musky, and freshwater bass flies. A must have for those who tie flies for predatory species.
