The ability for a man to tear decks of poker cards is a great measure of grip strength. All great grip athletes can tear decks of cards. Some men like Dennis Rogers have such great strength they can tear cards with just the index finger and thumb, and Dennis can tear them with one finger, one thumb while wearing oven mitts.
Clearly there is always room for improvement!
I have been working more and more pinch grip. I was foolish to ignore pinch grip for so long, but i will turn a weakness in to a strength.
