Frank WakefieldHaving tried it a variety of ways.... and almost messing up a card once...
What works best for me is a hammer and a screwdriver. I use the screwdriver as a chisel. Lay the holder flat on concrete, then tap around the very outer edge of the holder. It fractures. Patiently work your way around the edges. Eventually you can just lift out a big center piece and the card is free. MUCH better than getting a crack started, then prying, which is how I almost once folded a card.
