The Klinkhammer was devised by a Dutch angler Hans van Klinken, in the early 80's to imitate an emerging caddis fly to catch grayling and trout which feed on them as they floated in the surface film. This pattern has proven to be an extremely effective fly wherever caddis are found. Over time they were tied to imitate a variety of different emerging insects. Klinkhammers are different from many other parachute dry flies in that the thorax of the fly is designed to hang down below the surface of the water to imitate an emerging insect.
The secret is the caddis hook used allowing the abdomen of the fly to break the surface film and hang just below. We prefer the Mustad Signature hook # C49S in size 14-18.
The abdomen serves as a trigger point which penetrates the surface film, and gets noticed by trout from greater distances, long before fish spot a dry fly simply floating on the surface of the water.
Our Klinkhamer Selection contains a dozen flies in three different patterns, the original tan, pheasant tail, and blue wing olive. There are 4 of each pattern. Two #14 and two #18.
