The first dubbing twister in the world with a 100% dubbing loop control system. It is a modern designed tool, but still a classic fly tying dubbing twister. With a small pressure pinch (like a hackle plier) the loop can be opened to apply materials in the loop, then release to close the loop. Re-open as you need to add other materials like rubber legs, CDC, etc. The perfectly balanced design spins the loop and materials very smooth and tight.
