This is one of my favorite possessions. I've kept it on my desk for almost 30 years. It's from a museum gift shop and reproduces the pattern of a Victorian doorknob.
Not only is it a great paperweight, it fits beautifully in the palm of my hand, with just the right heft. Sometimes when I'm on the phone with someone difficult, I imagine giving it a good fling at that person's head. Empowering, that.
