The Knock Block isn't just a block of wood. It's not just a token of good luck to ward off those incidental jinxes. It's not just a life line to offer your friend or loved one in a time of need. It's not just the perfect gift to say "I care about your fate." It's not just that extra bit of confidence you get from the comforting sound of a good wood knock after you've cursed your entire future. It's a Knock Block!
