: What is the meaning of "I know it like the back of my hand"?

I really think I know the back of my hand very well. But it's right in front of me a very large percentage of the time, so the saying presupposes that one know's the back of one's hand very well. Hence, to know "it" that well is to know it very well indeed. SS
