Fart Juice Cards. Knife's Blunt
Don't underestimate the value of counter cards.
The Knife's Blunt card is a counter card. You can tell that immediately because it has a pink stripe.
You play the Knife's Blunt card when someone plays a Cut the Cheese! on you. It stops them from looking at your hand and taking a card. So it operates like the Fresh Undies card does to a Shart! The difference is that there is only one Knife's Blunt card in the deck, whereas there are 4 Fresh Undies cards.
Whenever you are holding a Cut the Cheese! card you are pretty certain of being able to look at and take a card from an opponent's hand. When he or she plays the Knife's Blunt card to block you, you suffer a moment of unmitigated chagrin! It always irks me far more than having my Shart! blocked by a Fresh Undies.
