This Tube Fly Tool (or Starter Tube Tool, as HMH modestly call it) is an inexpensive, yet extremely practical and versatile tool which may be easily and quickly fitted to any standard fly tying vice head, allowing the fly tyer to hold a range of tubes securely for dressing a wide variety of tube flies. It is well suited to holding Grays Needle Tubes in lengths from 15mm upwards, as shown here. In addition, the adaptor will hold conventional fly tying tubes or any of the growing number of new tube styles now widely available to the fly tyer.
