Dry FliesKlinkhammer
The Klinkhammer is a classic emerger pattern designed by Hans van Klinken that rides with the body suspended below the surface film while the hackle and thorax float on top. This unique profile perfectly imitates mayflies in the vulnerable moment of emergence. Available in Baetis and Zebra variations to match different hatches.

Overview
The Klinkhammer was developed by Dutch tier Hans van Klinken and has become one of the most effective emerger patterns worldwide. The curved hook design allows the body to hang below the surface while the parachute hackle and thorax remain visible to the angler. Blue Ribbon Flies offers both Baetis and Zebra variations to cover different hatch situations.

Fishing Tips
Season
Effective throughout the mayfly season from March through October. The Baetis version excels during BWO hatches, while the Zebra version works as an attractor during various emergences.
Presentation
Dead drift in the surface film. The pattern automatically assumes the correct position with the body hanging below the surface. Focus on feeding lanes where emergers collect.
When to Use
Best during mayfly emergences when fish are taking emergers rather than duns. Particularly effective when you see fish bulging or porpoising, indicating subsurface feeding.
Water Type
Ideal for spring creeks, tailwaters, and any water with consistent mayfly hatches. The design works well in both flat water and moderate currents.
Rigging Suggestions
Fish on 10-12 foot leader with 5X-6X tippet. The unique hook design makes hook-ups reliable when fish take the fly. Keep the hackle dressed with floatant.
Visibility & Floatation
The parachute hackle provides excellent visibility and floatation. The body naturally hangs below the surface, creating the ideal emerger profile without any additional weight.
