You might like this one if you appreciate fine craftsmanship.
Who says inventors and craftsmen weren't sharp 330 or so years ago? A master craftsman is difficult to come across but, I'm going to share a working piece of art with you. It's called, the Wilkes Detector Lock. I'm sure you will be as amazed and fascinated as I was and still am.The lock was created by a British locksmith named John Wilkes around 1680 or so. I hope you are wowed by this video.
