Fish Saver. Waterworks - Lamson's breakout product in the fly fishing industry, years ago, they thought: “There’s got to be a better way to remove a delicately-tied fly from a hooked fish than the hoisting, clamping, and wrenching process now on display.” So they created a simply innovative tool capable of reducing fish mortality by eliminating netting and handling—then named it after their home-base of Ketchum, Idaho. This technique will preserve protective coatings and eliminate air exposure. The Ketchum Release® tool makes low-mortality release easy, plus allows you to retrieve your fly without damage. It even keeps your hands high and dry. The Ketchum Release® is available in three sizes: Big Bug for hook sizes 6-10; Standard for sizes 12-16; and Midge for sizes 18-22.
