doug goodmanI use a rounded blade kitchen knife, starting on the top right corner. I've done hundreds of them, most recently this afternoon after the mailman delivered a 5.5 Topps 1952 Ivan DeLock and 2 different 1982 Topps blackless graded 8. Go slow, and be careful. I split 3 full edges before I open the slab like a book and remove the card.
Best of luck,
Doug
