The best possible combination is one of the C&F midge boxes and a fly spinner from Feather-Craft. The latter is a small cross-lock tweezer that one can use to pluck the smallest fly from the C&F box, then thread the tippet and spin the tweezers to make a clinch knot.

Since the spinner is a cross-lock, one need not keep pressure on to hold the fly in place. Drop everything (or a few things, as I often do) and the fly is still in the tweezers, just waiting to be knotted into place.

Best gadget EVER. I fish tiny flies all the time, and this tool makes it easy.
