Thank you for finding that! Why didn't Engadget or the New York Times put that photo into the article? Engraving kitchen knives with your ID number sounded like hyperbole. Nothing proves it like a photo or video. Same with articles on security or privacy compromises -- you need an actual exploit before (most) people take it seriously.
