"Eddie the Wire thought he'd written all he could about lock picking and the like, and then he came across some old mimeographed pages by the man who made the tools for Houdini. Eddie was again inspired and came up with some magic of his own. Eddie's Iron is truly new and revolutionary, so different in its concept that it was kept under wraps while the book was being produced. Follow Eddie's advice and make your own superior Eddie's Iron now - if locks interest you or picking a lock presents a challenge that you can't resist, then this book's for you! For Information Purposes only."
I suspect it's nothing exciting, but I am pretty curious. Has anyone read this book? What's the 'new and revolutionary' method it's about?
