A very little research found some more videos, suggesting this idea of a possible use of this tool for knitting gloves, has been around for at least 9 years. This brief video gives an idea of how to do multiple fingers on a single Dodecahedron and how to use it to knit the body of the glove also.
Beau's video refers to an earlier experimenter implying that these tools were found in different sizes. However, that still leaves me wondering what an experienced Nalbinder would do, at least for larger sized hands.
I'm still having cognitive issues with the different sized holes. If the stitches are the same size and coming off pegs which are all identically spaced, I don't see how the size of hole makes any difference. It would rely on the stretchiness of the knit to change the size of the finger tube, unless there's some way to increase the number of stitches in one circle.
