Klinkhammer

Hans van Klinken's curved hook design is a stroke of genius — the abdomen hangs below the surface film while the wing and hackle stay afloat above it, perfectly mimicking an insect stuck in the shuck mid-emergence. Highly effective during any mayfly or caddis hatch when trout are visibly rising but ignoring standard dry flies. Works in both stillwaters and rivers.

Materials

  • hook: Curved emerger hook #12–18 (Partridge Klinkhammer or equivalent)
  • thread: Match body color, 8/0
  • body: Dubbing to match hatch (olive, yellow, tan), slim
  • thorax: Peacock herl or darker dubbing
  • post: White or orange poly yarn, upright
  • hackle: Dry fly hackle wound parachute-style around post

Tying steps

  1. Mount a curved emerger hook (Partridge Klinkhammer or similar) with the bend hanging down; start thread at the bend.
  2. Dub a slim tapered abdomen in the appropriate hatch color on the curved part of the hook, stopping as the hook straightens.
  3. Tie in a poly yarn post at the elbow point of the hook, standing upright.
  4. Dub a fuller peacock or contrasting thorax dubbing forward to behind the eye.
  5. Tie in a dry fly hackle at the base of the post.
  6. Wind 5–6 turns of hackle parachute-style around the post, working downward.
  7. Capture hackle tips with thread wraps and build a small, neat head.
  8. Whip finish and apply head cement to the thread wraps at the post base.
