Snag, Arrows is what I do and all the guys say I'm anal about them, (but they never tell me not to do it).
I use a dremel sanding drum and mill off the ragged edge off the die cut feathers to a tapered point. Then just hit the point of the feather with a downward stroke. It really helps to do it before fletching, and then with a dab of glue after the feather is on the shaft, there is never a hump or sharp edge. It makes a nice clean, uniform looking fletch.
It seems like more work than it is and only takes a minute or two to do the whole 36. I love your arrows. There is never too much effort to make em how you want.
