On August 7, 1974, Philippe Petit stepped out on a wire illegally rigged between the New York World Trade Center's twin towers, where he performed for nearly an hour. During this history-making walk, and many others throughout his celebrated career, knots have always been indispensable components-the guardian angels protecting his life in the sky. After years of hands-on research, Philippe presents Why Knot?, a guide to tying his essential knots. Philippe's own practical sketches illustrate original methods and clear, clever tying instructions. Photographs in which special knots were used during spectacular high-wire walks, quirky knot trivia, personal anecdotes, helpful tips, magic tricks, and special tying challenges ensure that, if you're not already nuts for knots, Petit will transform you into a knot aficionado.
