Description
The Sedge-hammer Fly, created by renowned fly tier Hans van Klinken, is a highly effective dry fly designed to mimic adult caddisflies. This pattern excels in rough or fast-moving water due to its buoyant design and realistic profile. Typically tied on hook sizes 12-16, it features a wing made from natural deer hair for buoyancy and visibility, a dubbed body to match natural caddis colors, and often a hackle wrap for added surface tension.
Pro Tip
Fish the Sedge-hammer with short, twitchy strips to mimic a skittering caddis—it triggers aggressive strikes from trout during active hatches.
