Sometimes you stumble upon a tool you need without knowing you needed it, and the Terra Hackle Guards are just such tools. This simple tool set is designed to push back and protect stubborn material like brushes and palmered hackles so that finishing wraps, half hitches, whip finishes, and even cementing can be completed without trapping and thus misaligning errant fibers, thereby ruining the look of your carefully tied fly. Each of the three guards included in the package has a different size hole to accommodate different size hook eyes.
