To form the Mechanic's Grip, first hold the deck in your hand in the same fashion you might hold a hammer or tool. The cards should be lying flat in your palm with the longer side of the deck lying along the fingers. Take your pointer finger and move it to the short side facing away from you. Take your middle finger, ring finger, and pinkie finger and place them on the long side of the deck. Finally your thumb holds the deck together on the long side opposite of the other fingers. With this grip, more of the deck should be covered by your hand, thus making it more difficult for spectators to see what you are doing.
