"Why Didn't I Think of That?": Magnetic Wristband

It was only a couple of weeks ago that I was repairing some post and board fence and experiencing two lovely sensations: 1) the taste of fresh screws I was holding in my mouth and 2) the piercing of the failed steel nails I removed from the fence and stored in my jeans' pockets. This little gadget would have helped me with both. It's $19.50 and I bet it will be $9.99 by the time I'm looking for stocking stuffers!
