The short version for those of you just tuning in: edge-notched cards have the entire typosphere abuzz, but there is some question as to the best tool for punching out the titular edge notches without falling victim to dangling chads.
I presented the conundrum to the Mrs., to which she immediately responded "Oh, you mean like a ribbon punch."
Yeah, sure, why not?
Anyway, presented below is a picture of the thing that may solve all of your new-found notching woes. You'll have to excuse the bad photography and hasty hole-punching, but the animus is there. The first pic is a demo, and the second is me trying to show you what the punch itself looks like. If you can't discern it, think of a sharp metal "pause" symbol.


The only issue that I can foresee is that the one I have is a tad big in bore, but you might be able to find them smaller. Personally, I like the larger ones, what with my BDHS (Big Dumb Hands Syndrome).
Hope this'll do the trick!
