The HDB is the hook of choice for tying a blob fly on a heavy-wire frame. The shank is short, but the diameter of the tufting can quickly fill the gap between the shank and the point. Therefore, size the hook based on the volume of the fibers, not just the length of the fly. Fold the chenille backward with each wrap to release the fibers rather than trapping them under the next wrap. The HDB has a Black Nickel finish and is sold in packs of 25.
