The half-cut binders were custom made, as a Kickstarter stretch goal. If you want card binders meant to make it easy to get cards in and out, instead of difficult, you're going to have to break out a sharp hobby knife or a box cutter.
The official binder pages were custom made thanks to Kickstarter Stretch Goals. It's very possible to make your own though, I did for the Print and Play before I got my Deluxe Set. Get some Ultra Pro pages and an Xacto knife, and cut a line at the top of the seals that separate the cards from each other. It helps if you put in some junk cardstock or cardboard in the pages so you don't cut all the way through. If the knife is new and you use a straight edge, you should have no trouble getting a straight, clean cut.
It's time consuming, but very much worth it considering how often you move cards in and out of the pages.
