Last night at dinner in San Francisco (I’m in town to give a Long Now talk tonight), our waiter noticed that I was wearing a ring made from an ornate spoon handle and produced his home-made money-clip, which he’d fashioned from an antique butter-knife he found at a pawn shop. He said he’d used a hand clamp to hold the handle, wrapped the blade in a cloth dishtowel, and used careful hammer-taps to bend it around. He also said that he flew with it routinely without any problems from the TSA. It was a really nice piece — he wrapped his bills around his credit-cards and ID to create the necessary thickness.
