Unbeatable Nor-Vise As experienced fly tiers know, the revolutionary rotary Nor-Vise has advantages over other "rotary" vises. Combined, these advantages make the Nor-Vise a tool of both art and science — yielding a lifetime of fly tying success. Centerline Perfection Nor-Vise positions the hook on a perfect rotational centerline, allowing the hook be spun, replacing tiresome hand-over-hand wrapping. With the shank of the hook always aligned to center, the material is "turned" or "spun" onto the hook. This is a real labor and frustration saver. Body Material, Hackle and Dubbing Precision ball bearing and heavy brass hubs enable Nor-Vise to work like a spinning wheel for the world’s most fluid dubbing, creating perfectly shaped and textured bodies. Working thread, other body materials and hackle are applied better, faster and easier than by any other method. Tube Fly Conversion This Conversion is designed for fly tying on tubes which are strung onto a leader normally with a small short shanked hook. Very effective patterns especially for large aggressive game fish can be created which also cast quite well. The Nor-Vise Tube Fly Conversion comes with four mandrels, matching collars and will accommodate a wide range of tube materials, sizes and types. The tubes can be rotated, spun and locked on perfect rotational centerline and will not slip, turn or move. Includes a matching Thread Post, Mounting Bolts, Operating and Set-up instructions, Hex Wrench, and a hour-long instructional video.
