Daiichi 1730 Fly Tying Hooks 8 25 pack

From AvidMax.com

This hook was specifically designed to enhance the "oenatural appearance" of stonefly nymph fly patterns. In older fly tying recipes, tiers were often instructed to bend the hook shank of a typical 3X or 4X-long hook down, that way the final product exhibits a curved or bent body more closely resembling the actual nymphs which bend between the thorax and abdomen when they free swim. Manually bending a finished hook always compromises the metal and is not recommended. These hooks come pre-shaped for perfect looking imitations.
