Of all the fly threaders I have ever used or seen, this one is by far the best - that is because it works! Not only that, it is simple to use, light weight and can hang around your neck.
As the diagram says, simply put your fly hook in the groove, push through on the line and the line is through. It takes a lot of frustration out of a day or nights fishing, especially when it is getting dark!
Highly recommended.
