Overview

The Bonecrusher is a proven saltwater fly for targeting bonefish in deeper flats. It's tied with a heavily weighted body—usually lead or bead chain eyes—on a saltwater hook. The body typically uses tan or olive synthetic dubbing, with rubber legs and a wing of craft fur, Arctic fox, or synthetic fibers for movement. Flash accents and a weed guard can be added depending on the terrain. The key in tying this pattern is balancing the materials to maintain a quick sink rate while preserving a natural profile and subtle movement.
