Halving or tearing a deck of cards is when you tear it in two. Then you can tear one of these halves in two, which means quartering a deck of cards.
I’ve been working on my card tearing again lately and this video marks a PR for me. I’ve quartered plenty of decks before, but none with as tough of cards as this. The casino decks of cards I’ve been working with are much tougher than most cards, including the Bicycle deck, which is considered the Gold standard of card tearing.
I’ll be working on speeding up this tear and progressing to even more cards. My main goal here is to be able to eighth a deck of cards, which is taking one of the quarters and tearing it in half again!
