Your Pinky Finger Provides 33% of your hand’s grip strength

While your index and middle fingers work together with your thumb – buttoning or unbuttoning or pulling up zippers, your ulnar digits (little and ring fingers) join forces and produce up to 55% of your hands overall grip strength, of which your pinky is responsible for 33% of this combined strength. Don’t believe it? Without using your pinky, try doing a pull up… you’ll probably find that your little finger is indeed very useful and strong to boot!
