Frank WakefieldAfter trying it lots of ways with various tools, eg hack saws, vices...
Lay the slab down on a hard surface, concrete is good.
Place blade of a large flat blade screwdriver just inside the ridge of the edge, and tap it with a hammer. Patience is good. I almost bent a card where I was in a hurry to get it out, and pried open the front and back after I'd cracked open a side. Don't pry. Keep tapping around the edge until it comes apart. Then you can lift out the card.
I finally started saving the little SGC and PSA slips... I've not sent anything in to them letting them know about the liberated card. But who knows, one day I might become a slabhead and wish I'd kept 'em.
Patience.
